About Barzahlen
General information about Barzahlen
This manual describes configuring and using the Computop interface for Barzahlen:
Barzahlen is aimed at customers in Germany who do not want to enter 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.
Barzahlen is a payment provider for cash transactions. Customers use cash to pay for online purchases, travel bookings or diverse invoices. It is also possible to pay by cash to one’s own giro account.
The customer receives a barcode via email, SMS or Post to process the payment. This barcode is then scanned at the checkout of an individual partner branch and the customer pays with cash or another permitted payment method. The supplier is notified about payment in real time by the checkout system once the customer has paid. The payment service is carried out by Greensill Bank AG from Bremen.
Currently cash payments are made throughout Germany in over 10,000 branches of the REWE markets, dm-drogerie markets, PENNY markets, real,- supermarkets, Telekom Shops, mobilcom-debitel branches and with Budni chemists and in branches of the Dr. Eckert group.
Cash payments offer users who prefer cash, the option to buy, gamble or to book travel online without entering sensitive financial data. This cash option, means it is the only payment system available to every German without restriction. 68% of Germans over 18 years have no credit card (Deutsche Bundesbank 2015) and 51% do not use online banking (Bundesverband deutscher Banken 2014).

Batch processing via the interface
Basic information about using Batch files and about their structure can be found in the Batch Manager manual. Within batch processing not alle functions are available which are usually available for the online interface.
This section describes the parameters which must be transferred within the data set (Record) for executing reversals or credits with Barzahlen and which information can be found within the response file about the payment status.
For Batch calls there must be considered batch versions, from which optional parameters depend. All version designations starting with „2.“ pertain calls for a group of enterprises. That means within a batch file for a particular MerchantID can be transferred transactions for other merchants with a separate Sub-MID.
Following table gives an overview of all batch versions that are possible for a specific action and their specialities:
Action | Version | Description |
|---|---|---|
Credit | 1.0 / 2.0 | Standard version without return of parameter Code |
1.x / 2.x | with RefNr (valid for all versions other than 1.0) | |
| Reverse | 1.0 / 2.0 | Standard version without return of parameter Code |
1.x / 2.x | with RefNr (valid for all versions other than 1.0) |
Description of the possible batch versions
The structure for a Barzahlen payment within a Batch file to be submitted is the following:
HEAD,<MerchantID>,<Date>,<Version> Barzahlen,Credit,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID> Barzahlen,Reverse,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID> FOOT,<CountRecords>,<SumAmount>
Example for Master MID function:
HEAD,[Master]MerchantID,Date,2.x Type,Action,[Slave]MID,Amount,Currency,TransID,Data (depends on Action) FOOT,CountRecords,SumAmount
The following table describes the individual fields and values used within the data set (record) in the batch file:
Key | Format | CND | Description |
|---|---|---|---|
Type | a..11 | M | HEAD for Header, FOOT for Footer, Barzahlen for Barzahlen |
Action | a..20 | M | The parameter Action defines the type of transaction: Credit Reverse (cancellation) |
| Key | Format | CND | Description |
|---|---|---|---|
| Amount | n..10 | M | Amount in the smallest currency unit (e.g. EUR Cent). Please contact the Computop Helpdesk, if you want to capture amounts <100 (smallest currency unit). |
