This manual describes the programming of the Merchant Interface. Paygate also allows the submission of batch files. These are CSV files containing several payment orders which are transmitted to the Paygate. Paygate permits both manual as well as automated (FTP) transfer of batch files. You can find details of the batch process in the Manual of Batch manager.

Computop Analytics enables the merchant to manage transactions online. This is a web application with password protection and TLS encryption, which lists all transactions and also permits, for example, credits.

The POS Terminal is a clever alternative to the physical terminal and lets you process direct debits and credit card payments. You can find details about POS Terminal in the Computop Analytics User Manual.

Paygate uses numerical response codes which provide information about the transaction status. To determine success or error of a transaction more precisely, please analyse the response parameter Code. For a detailed breakdown of these codes, please see the Paygate Response Codes Excel table which is available at https://www.computop.com/us/downloads/.


Scope of services of Paygate

Overview of supported payment methods

The role of Computop’s Paygate is to receive and process payment requests and provide additional functions such as fraud prevention and protection of minors. Paygate has several interfaces for receiving transactions: A Merchant Interface for the shop-connection, a Batch Interface for payment orders in batch files and the POS Terminal for processing payments for telephone- and fax-orders. Paygate offers several payment methods and additional functions for payment processing:

Paygate fraud prevention

Paygate supports different processes for fraud prevention. These include inquiries with credit agencies in the monitoring of the card's country of origin and payment guarantees for credit cards.

Function

Description

Verification of the country of origin of the IP

A main part of fraud attempts comes from abroad. Paygate can check the country of origin and often even the city of the IP address which your customer has just used. If the country of origin of the IP address of your customers is not one of your supply countries or is not the same country as that of the credit card (see below) Paygate can send an alert via e-mail or automatically refuse the payment.

Verification of the card's country of origin

75% of all attempted frauds take place with foreign credit cards. Paygate can therefore check the card’s origin: If you enter the delivery country as a parameter, Paygate returns the country of origin of Visa- and MasterCard-Credit cards and sends an e-mail if the delivery country differs from the card’s origin. You should then find out from the customer why the card’s origin differs from the delivery country to avoid fraud. Paygate can optionally refuse such payments immediately.

Seller protection in the case of PayPal

PayPal offers seller protection via a delivery address comparison. Either the shop notifies the delivery address or the customer uses PayPal Express-Purchase and selects a delivery address lodged with PayPal. Paygate then forwards the address to the shop. If the Merchant verifies that it has delivered to the address specified with the payment, seller protection acts such that PayPal must deal with the claim itself.

giropay Pin/TAN query

The giropay online transfer based on the PIN/TAN online-banking process: The customer logs in with a PIN (Personal Identification Number) and then uses a new TAN (TransAction Number) for each payment.

Block list check and sales limits

To reduce your direct debit-risk Paygate can check the block lists of 70 major merchants, updated daily and containing approx. 1.5 million blocked accounts using the ELV Score: if any of your customer’s accounts is already in debt to another Merchant due to a shortfall in funds you can refuse the transaction and save on failed sales and chargeback costs. You can also prevent fraud by setting sales limits which a particular account may not exceed per day, week or month.

Address checks and credit ratings

Address check and credit ratings with all established credit agencies, e.g. arvato Infoscore, Bürgel, Creditreform, Universum Group, Schufa.

Schufa verifications

Schufa has data on 62 million bank customers. Paygate uses the IdentCheck to verify whether a person exists and whether a name matches the specified address. Additionally you can verify with the credit rating before the order whether there is a summary debt procedure against a customer or whether it has been reported in public debtor directories e.g. due to personal bankruptcy.

American Express address verification

Computop Paygate can carry out an address comparison with American Express to ensure that the customer is the correct card holder. If the street number or postcode does not correspond with the American Express data Paygate can return the result of the address verification within response parameter “Match”.

Verified by Visa, MasterCard SecureCode & American Express SafeKey

If you use Verified by Visa, MasterCard SecureCode and American Express SafeKey you benefit from a secure payment claim, should the customer dispute the payment. The so-called liability shift transmits the default risk to the card-issuing bank.

Verified/SecureCode/ SafeKey Authentication Hosting

If you only wish to verify the identity of the card holder without immediately activating a credit card payment, Paygate lets you simply inquire about the password with Verified by Visa, MasterCard SecureCode and American Express SafeKey. This authentication is valid for 90 days for authorisations and secures your payment claim.

Variable amounts for Verified/SecureCode/ SafeKey

It is sometimes not clear when the credit card data is input how much the subsequent payment will be. In this case Paygate can initially authenticate the higher amount with Verified, SecureCode or SafeKey. The card is not charged but you secure the payment guarantee for the overall amount, even if you subsequently authorise and capture only a partial amount. See also the Amount and Amount3D parameters.

Table: Paygate services for fraud prevention


Services for credit and debit cards

You can submit credit card payments and debit card payments either online via the Merchant Interface as a batch file or via the SSL-Terminal. The following table describes the services of Paygate for these payment methods:

Function

Description

Individual layout for payment pages

Anyone saving or transmitting credit card data must undergo extensive security authorisation, called PCI DSS Certification. You can avoid much of this by the use of Paygate forms using pseudo card numbers (see below). In order that the payment page complies with the shop-layout you can tailor the form with XSL-templates individually to your shop layout.

Authorisations

Verification of creditworthiness and validity of the credit cards and reservation of the amount on the customer's card account.

Authorisation renewal

An authorisation lowers the card limit of the customer and reserves the sale for your company. The authorisation is valid however for only approx. 14 to 30 days. To maintain your payment claim, Paygate can renew expired authorisations automatically until shipment takes place. The Paygate can also obtain a Verified, SecureCode and SafeKey payment guarantee in the case of authorisation renewal.

Partial authorisation for partial deliveries

Complaints may be made if a customer obtains a partial shipment but must pay in full. Paygate therefore permits part captures. The partial capture cancels the underlying authorisation. Paygate can then automatically re-authorise the outstanding amount in order that your payment claim is retained and the subsequent captures function. Paygate has been able to obtain a payment guarantee with Verified, SecureCode and SafeKey.

Captures

Capture is the second step after the authorisation which debits the reserved amount from the customer's card account. You can choose between manual or automated capture.

Capture On Demand

With Capture On Demand you can temporarily delay the automatic capture, for example in order to delay debiting of the money until after delivery. You can define a default delay and individual delays for each transaction, for example capture in 72 hours.

Credits

Paygate gives the opportunity to reverse payments with credits. You can execute the credit manually or link the process to your enterprise resource planning system.

Reversals

In Computop Analytics you have the opportunity to reverse authorisations, captures and credits. Unlike Credits, these Reversals do not appear on the customer's card bill. Reversals must be made on the same day.

Authentication Hosting

If you only wish to verify the identity of the card holder without immediately activating a credit card payment, Paygate lets you simply authenticate with Verified by Visa, MasterCard SecureCode and American Express SafeKey. The payment must take place within 7 days depending on the bank and the Acquiring Bank.

Fraud prevention

75% of all attempted frauds take place with foreign credit cards. Paygate can check the card’s origin: If you enter the delivery country as a parameter, Paygate returns the country of origin of Visa- and MasterCard-Credit cards and sends an e-mail if the delivery country differs from the card’s origin. You should then find out from the customer why the card’s origin differs from the delivery country to avoid fraud. Paygate can optionally refuse such payments immediately.

Batch transmission

Along with online-processing, Paygate permits payment processing with batch files, which you can transmit manually or automatically (SFTP). Paygate processes the payments in the file, saves the transaction statuses and provides the response file. You can also request the response file manually or automatically (SFTP).

Pseudo card number (PCNR)

Anyone who saves or forwards credit card numbers has to undergo extensive security authorisation in accordance with PCI DSS. You can avoid this by using Paygate forms. When you need credit card numbers, e.g. for subscription payments or repeat orders, Paygate generates a pseudo card number (PCNR) for the payment. Instead of the credit card number you only save the PCNR, which works exactly like the genuine credit card number. You can use the PCNR for authorisation, capture, reversal and credits. The credit card data is located only on the PCI-certified Paygate servers which saves you the costs of having to obtain your own authorisation.

Paygate services for credit card payments

 


Services for transfers and direct debits

You can submit electronic direct debits either online via the Merchant Interface, as a batch file or via the SSL-Terminal. The following table describes Paygate services for electronic direct debits:

Function

Description

PayPal, ELV, giropay

PayPal administers 15 million customer accounts in Germany. In the case of PayPal the user can pay via direct debit, giropay or credit card. Irrespectively of how the customer pays with PayPal, the Merchant benefits from PayPal seller protection.

giropay online transfer

giropay is a payment standard of German banks like Sparkasse (savings banks), Postbank and Volks- und Raiffeisenbanken, wherein the customer is connected directly with its banks' online-banking. Customers usually log-in with a PIN, receive a pre-completed payment transmit form and need only confirm with a TAN. If you use giropay via Paygate, giropay offers a payment guarantee up to 10.000 euros and you benefit from immediate receipt of payment.

iDEAL online transfer for the Netherlands

iDEAL is a payment standard of the Dutch banks where the customer is connected directly to its banks' online-banking. Its operating principle is similar to giropay (see above) but the payment guarantee is unlimited.

Block list check

To reduce your direct debit-risk Paygate can check the block lists of major merchants, updated daily and containing approx. 1.5 million blocked accounts using the ELV Score: if any of your customer’s accounts is already in debt to another Merchant due to a shortfall in funds you can refuse the transaction and save on failed sales and chargeback costs.

Captures

Paygate checks the plausibility of account data and enables the capture of the customer account. You can carry out the capture manually or instruct Paygate to do this automatically.

Austrian accounts

If you have a company account in Austria Paygate can also obtain direct debits from the accounts of your Austrian customers.

Capture On Demand

With Capture On Demand you can temporarily delay the automatic capture, for example in order to delay debiting of the money until after delivery. You can define a default delay and individual delays for each transaction, for example capture in 72 hours.

Reversals

It is not possible to refund direct debits, however, you can reverse the capture until your direct debits have been transmitted to the banks for that day. The reversal must take place on the same day.

Batch transmission

Along with online-processing, Paygate permits payment processing with batch files which you can transmit manually or automatically (SFTP). Paygate processes the payments in the file, saves the transaction statuses and provides the response file. You can also request the response file manually or automatically (SFTP).

Payment methods available

This chapter gives a short introduction to the operating principle of the payment methods offered by Paygate. The descriptions do not concentrate on the technology but on technical aspects from the perspective of merchants and customers.

Credit card payments with TLS

The credit card is a widely used international payment tool on the Internet. Transport Layer Security (TLS) is successor of Secure Socket Layer (SSL) and an asymmetric encryption method in the Internet which protects credit card data against tapping and manipulation, during transfer for example. In the case of credit card payments with TLS the card holder enters the credit card data in a form which is encrypted with TLS.


Entry form with TLS-encryption for credit card data


For safety reasons an SSL certificate is required for TLS-encryption.


Transaction procedure with TLS-credit card payments

In the case of TLS-payments the customer chooses the Credit card payment method at the Internet checkout. The customer is then requested on an TLS-encrypted page to input the credit card number and expiry date. The Paygate receives the credit card data and then processes the payment.

Credit card payment with TLS checks the credit limit of the customers but offers no protection against fraud using stolen card data. Please note therefore the security processes Verified by Visa, MasterCard SecureCode and American Express SafeKey in the following chapter.

In the case of American Express payments Computop Paygate can protect against fraud by comparing the order address with the address stored at American Express: Computop Paygate carries out an address comparison with American Express to ensure that the customer is the correct card holder. If the street number or postcode does not correspond with the American Express data Paygate will either refuse the payment or send you an alert by e-mail.


Credit cards with Verified by Visa, MasterCard SecureCode and American Express SafeKey

MasterCard SecureCode (UCAF), Verified by Visa (VbV) and American Express SafeKey are authentication methods which verify the identity of the card holder before making the payment. The name 3D Secure used by technicians describes only the protocol. The correct brand names are Verified by Visa, MasterCard SecureCode and American Express SafeKey.

Merchants benefit from authentication with Verified by Visa, MasterCard SecureCode or American Express SafeKey because the card associations enact a liability shift: If you use Verified by Visa, MasterCard SecureCode or American Express SafeKey you benefit from a secure payment claim, the liability shift transmits the default risk to the card-issuing bank,  should the customer dispute the payment. Irrespective of whether the card holder actually uses the authentication you obtain in effect a payment guarantee in case the customer asserts that it has not implemented the credit card payment itself.

From a technical perspective Verified by Visa, MasterCard SecureCode and American Express SafeKey are not payment methods but an authentication process which precedes the payment: Once the credit card data has been entered, Paygate checks the identity of the card holder and does not process the payment until after the authentication.


Transaction procedure with Verified by Visa, SecureCode or SafeKey

The customer selects the Credit card payment method in the Internet shop and enters the card number and expiry date. Paygate receives the card number and checks, via a connection to Visa, MasterCard or American Express, whether this credit card is registered for Verified, SecureCode or SafeKey. In the process the transaction is given a marking which identifies Verified by Visa, SecureCode and SafeKey payments. This marking tells the Acquiring Bank that you use authentication and a secured payment claim is obtained based on the Visa Liability Shift in case the card holder disputes the payment. If the credit card is not registered a credit card payment is carried out with TLS.

If the customer's credit card has been registered by the issuing bank for Verified by Visa, MasterCard SecureCode or American Express SafeKey the authentication process now starts: Paygate opens a new browser window which connects the customer to its bank. In this window the customer enters the password received by its bank.

If the password is correct Paygate obtains confirmation in the form of a signature. Only after confirmation does Paygate start the payment and send the transaction with the signature to the Acquiring Bank.


ELV Score: Direct debit with block list check

Paygate can combine SEPA direct debits in Germany and Austria with a block list check which offers high security at low cost: Paygate firstly checks whether the Customer's account number is black listed by major retailers. Secondly you can prevent fraud by setting sales limits per day, week or month which an account connection may not exceed.

Since there are substantially more accounts than credit cards, many Internet purchases are paid for by direct debit. The direct debit process is unsafe for merchants without a block list check: in the case of SEPA direct debits there is no authorisation because it is not possible to carry out a credit rating on the account of the customer. There are frequently return debit notes due to lack of funds in accounts.

The block list check links the benefits of the direct debit with the security of a block list check and individual sales limits.

Paygate can now draw a direct debit not only from German but also from Austrian or Netherland customer accounts. The precondition for this is a company account in Austria or the Netherlands.

Transaction procedure of a direct debit payment on the Internet

In order to pay with a direct debit, the customer selects the Direct debit payment method at the Internet checkout and enters his account details on an Internet page. This Internet page is TLS encrypted to protect the account data during the transmission against tapping and manipulation. After the input Paygate checks if the IBAN is plausibly, whether the account is blocked and whether the sales limit for this account has been reached. After successful verification, Paygate draws direct debits from the customer's bank.

International direct debit payments via PPRO International Direct Debit (IDD)

Electronic direct debits over Paygate are possible in UK, the Netherlands, Austria and Spain for all accounts of appropriate banks, but offer no block list checks. For customers the payment by entering their banking details is convenient and secure, because the 8 weeks period for chargebacks applies here too. The merchant gets a real-time payment, but bears the risk of possible chargebacks.



Money transfer with giropay, eps, iDEAL and DIRECTebanking

Computop Paygate supports online transders with giropay in Germany, with iDEAL in the Netherlands, with eps in Austria and DIRECTebanking in Germany, England, Austria, Switzerland and the Netherlands. A number of surveys of Internet users verify that transfer is a popular and accepted method of payment. Computop Paygate therefore supports this convenient, secure payment procedure. The customer potential for online merchants increases to around 20 million online-banking customers with the use of online transfers.

giropay is a standard which was founded by the German banks Sparkasse, Postbank, Volks- und Raiffeisen Banken. The giropay online transfer has a number of advantages for merchants. Firstly giropay provides the vendor with a guarantee for payments of up to 10,000 euros; secondly the transfer is a prepayment which minimises the payment term. Last but not least the customer is using the familiar and trusted online banking of its own credit institution, just the same as with online banking.

giropay links customers directly to their banks


Dutch banks established the iDEAL money transfer standard, which works in a similar fashion to giropay in Germany. Approximately 70% of all e-commerce payments in the Netherlands are processed with iDEAL. Therefore offering iDEAL is a vital success factor for e-commerce business in the Netherlands.

In Austria Computop Paygate supports online money transfer with the Austrian Electronic Payment Standard (EPS) which is a well established system in Austria and offering a payment guarantee to the merchant.

Computop Paygate supports SOFORT transfer of SOFORT AG in many countries in Europe. Currently supported countries can be found on the webpage https://www.sofort.com/ger-DE/verkaeufer/su/e-payment-europaweit-mit-sofort-xxl/. SOFORT Banking is a method of bank transfers and is based on online banking. The customer selects SOFORT Banking as payment method for their online purchase and then will be forwarded to the secured payment form. The bank transfer data will be transferred automatically and the customer only has to select his or her bank and enter their usual login details for online banking. The consumer then releases the bank transfer by means of an approval code. All data is send encrypted to the online banking account. The online merchant receives a real-time confirmation of the executed bank transfer. The merchant can execute and dispatch the order immediately delivering goods/services faster. There is no waiting time until the dispatch of the goods like it would be for example in the case of prepayment via bank transfer.

Example of an online transfer procedure with giropay

In the first step the customer chooses the giropay payment method at the checkout of the online shop and selects its credit institution. The customer is then connected directly to its Sparkasse/bank and logs on as normal using a PIN. A pre-completed transfer form then appears. The customer need only enter their TAN to confirm the payment.

In the Netherlands the procedure of an iDEAL online transfer is similar but there is an unlimited payment guarantee.

As usual with online banking, the data disclosed in the online transfer is encrypted with TLS (Transport Layer Security) to prevent manipulation.

Checkout by Amazon is available in Germany, Great Britain and the USA. Amazon.de alone has around 16.7 million customer accounts. Amazon customers know the ordering procedure and trust it. This trust and the familiar procedures can improve the conversion rate of your shop. Last but not least, Amazon Payments offers a payment guarantee.

Amazon makes these details available to the Computop Paygate, which then handles the payment procedures. Due to the integration of Amazon, the customer is informed about the payment and the dispatch of the articles by email, as he is used to from Amazon.


PayPal Express Checkout

Computop Paygate lets merchants process PayPal payments. It lets you receive payments from 230 million PayPal-customers worldwide. 15 million Internet users own a PayPal customer account in Germany alone.

PayPal offers its users several payment methods

 

PayPal was a subsidiary of eBay and is widespread amongst eBay users worldwide. The old PayPal-standard solution however has required manual processing for reasons bound up with the history of eBay. Computop Paygate offers fully-automated payment processing with PayPal Express Checkout for mass mail-order business. Thanks to its automation in Paygate, PayPal Express Checkout is also suitable for processing larger transaction quantities, for example in the mail-order business. The manual processing of e-mails and payment processes which is normal for the PayPal-standard solution are a thing of the past.

Customers in more than 100 markets

PayPal is particularly useful for customer purchases abroad since Computop Paygate supports all currencies and markets offered by PayPal. In many countries PayPal offers customers typical payment methods for their country. A German customer can thus have the option to pay with PayPal by credit card, direct debit or with giropay-transmit. Customers abroad can often use typical payment methods such as prepaid cards in Italy or debit cards in the UK. Integrating PayPal into your shop therefore provides your customers with several payment methods at once.

Seller protection and address verification

Computop Paygate also provides you with the PayPal risk management. With address verification and PayPal seller protection PayPal relieves the merchant of the risk of payment failures in the case of direct debit payments, German credit card payments and unjustified customer complaints.

PayPal Express Checkout Fewer order cancellations

Long order processes increase the rate of cancellations. Computop Paygate offers the PayPal Express Checkout to shorten the order process: your customers do not need to enter any address data but rather click on Checkout with PayPal in the shopping cart area, log on and select the invoice- and delivery address retained by PayPal. Paygate then sends the delivery address as a result parameter back to your shop.

PayPal Express Checkout button

 

If the customer selects Continue to Checkout instead of PayPal Express Checkout in the shopping cart area, PayPal is displayed again as a payment method on the payment page. Selecting PayPal lets your customer log into PayPal to confirm the payment. In this case it is important that the delivery address is transmitted to ensure that the PayPal seller protection is activated.

Process optimisation for PayPal payments

Along with standard processing, Paygate supports more complex supply processes with PayPal. As with credit cards you can also reserve an amount for PayPal payments which you can then capture via the usual interfaces. In this way you do not charge your customers until the goods have been shipped.

Paygate supports all transaction types as required for optimal completion of your processes. We are happy to provide you with consultation (if necessary with our colleagues from PayPal).



Wallet systems: Skrill (Moneybookers) and QIWI

Skrill from Moneybookers has around 21 million, mostly younger, account holders from the gaming sector, ranks alongside PayPal as one of the world’s largest wallet systems for online payments. Skrill is available in 200 countries with 41 currencies and offers merchants a payment guarantee without chargebacks as well as the possibility to process credits (refunds).

        

Logos of Moneybookers and QIWI

 

Since 2007 the QIWI Wallet has developed into the largest alternative payment system in Russia with over 400,000 transactions daily. Success is also because cards are not very widespread and only 5 % of the population of Russia have a bank account. The QIWI Wallet can be topped up quickly and flexibly and used for guaranteed payment. Various access options exist for this, even including an iPhone app. Worldwide, QIWI is already available in 20 countries such as China, India, the USA and Brazil.

Guaranteed payments on invoice

Computop offers you as a merchant the greatest possible flexibility in that you can freely choose the best system of invoice purchases for your particular business. The following providers all give a guarantee of payment although their processing, price and geographical reach differ:

Full service from Klarna and RatePAY

With Klarna and RatePAY you profit as a merchant from a full invoice and hire purchase service. All you have to do is pass on all the invoice data during the order to the service provider, who then takes over the complete billing and debtor management. That than takes over the complete billing and debtor management. Your customers gain financial flexibility with Klarna, since they can choose between invoice purchase and hire purchase. Furthermore RatePAY offers classical hire purchase and SEPA direct debit.

Klarna already offers invoice purchase and hire purchase in many European countries.

As a Paygate customer, two systems are available to you for purchase by instalment with payment guarantee: With Klarna and RatePAY, online approval for the purchase by instalment is given in a matter of seconds during the order process. A PostIdent-process is not necessary. Klarna and RatePAY transfer the invoice amount rapidly to the merchant and bear the non-payment risk themselves.

As merchant you benefit from rapidly available liquidity. With Klarna and RatePAY your customers increase financial flexibility, as they can define the instalment amount themselves.



Debit payments in England and Denmark

Debit cards are more widespread in Europe than credit cards. Direct debit, bank- and savings banks cards (formerly ec-Cards) are extremely popular in Germany. Our European neighbours also prefer to use debit cards. Computop Paygate therefore supports Maestro in England and the Dankort in Denmark.

With 23 million card holders, Maestro offers huge customer potential in the UK.

Notice: In the UK Maestro replaces the old Switch/Solo-Cards. It works there without SecureCode but does require an address verification. Outside the UK Maestro functions worldwide only with SecureCode (see also next chapter).

     

Logos of the debit cards in France, England and Denmark


In Denmark you can reach around 3.5 million card holders with the Dankort-solution. The significance of Dankort is also demonstrated by the fact that the Danes make 535 million payment transactions annually using the Dankort.



Maestro worldwide and in UK

250 million people in Europe own a Maestro card. Maestro offers a potential of 570 million customers worldwide. In the UK Maestro replaced the former Switch-Cards and therefore works a little differently to the rest of the world: Paygate offers Maestro with address verification for the UK and Maestro SecureCode worldwide.

Notice: Maestro with SecureCode does not function in the UK for all cards!

The customer potential of 570 million Maestro card owners worldwide is very attractive for merchants with customers abroad. Since 2006, 250 million card holders in Europe, for example the British and the Austrians, have been able to use their Maestro card on the Internet. However while the Austrians must first apply for a SecureCode password to use their Maestro card online, 23 million British people can now use their Maestro on the Internet without a SecureCode.

Logo from Maestro

 

All current payment solutions for Maestro to date however only work with SecureCode, which the 23 million British card holders do not have. Therefore Computop has equipped its Paygate payment platform with two Maestro solutions: Paygate supports the worldwide standard of Maestro SecureCode but also processes Maestro with British cards without SecureCode. In the UK SecureCode is used with integrated address verification. You can therefore reach all Maestro customers with Computop Paygate, including the 23 million English Maestro card holders.

Along with worldwide distribution, Maestro has several benefits for business: firstly the discount costs are generally lower than with credit cards and secondly you benefit from shorter payment terms. Business also benefits from a secured payment claim in the Maestro SecureCode. Maestro therefore has much to recommend it, particularly for merchants with customers abroad.



paysafecard and Barzahlen

Computop Paygate supports prepaid payments with paysafecard. On the one hand these are prepaid cards that your customers buy in shops in order to subsequently shop online. Since this is a prepaid means of payment, these systems are free from chargebacks. In addition it offers merchants a payment guarantee.

          

Logos from paysafecard and Barzahlen

 

Paysafecard is widespread in the gaming, gambling and adult content sectors. You can tap into additional target groups with this prepaid system:

  • customers who do not want to disclose personal data such as bank account or credit card number
  • young people who are denied access to classic payment systems such as credit cards
  • customers who do not obtain a credit card from their bank
  • as well as customers who prefer to pay with paysafecard

The prepaid system is international: the paysafecard Group operates in more than 40 countries in Europe as well as in North and Latin America and processes around 20 million prepaid payments annually.

Barzahlen is aimed at all customers in Germany who are unwilling to enter their sensitive data online, and those who do not use credit cards or online banking. An alternative to cash on delivery, Barzahlen is quicker and less expensive. Customers pay the amount to an associated retailer, on the basis of a payment form; the retailer transmits a payment confirmation in real time to the online shop so that the goods can be dispatched quickly.

Address-checks and credit rating

Popular with customers, risky for the merchant: Payment methods such as direct debit or purchase on account involve a high level of default risk. Computop Paycontrol is an automated credit rating working in conjunction with all standard credit agencies, combines flexibility and payment security for online business.

SecurePay is integrated directly into the Computop Paygate online payment platform. This saves time-consuming and laborious manual enquiries to credit agencies on the part of the merchant. SecurePay lets you access information automatically from arvato infoscore, Boniversum, CRIF and Schufa without linking your shop system to individual credit agency interfaces.

Logos from providers of address checks and credit ratings

 

As it is integrated into the interface between the online shop and Computop Paygate, if a customer gets a negative credit rating the merchant can react quickly and automatically and offer the customer, for instance, only payment methods with a payment guarantee at the checkout. SecurePay thus protects the merchant from payment defaults as far as possible without foregoing sales.

The use of SecurePay gives online merchants many more options in addition to credit card acceptance while minimising the risk, enabling them to compile individual payment options including electronic direct debits and even purchase on account for their customers. The pre-transaction credit rating means maximum possible payment security for the merchant with a substantially greater and therefore more customer-friendly package of payment methods.
