About Bluecode
General information about Bluecode
What is Bluecode?
Bluecode is the first pan-European mobile payment solution that enables cashless payments via Android smartphone, iPhone and Apple Watch combined with value-added services in a single technology platform. In accordance with European data protection standards, no personal data is ever exchanged with participating banks or merchants thus none is stored or transmitted on the mobile phone during the payment process. The highly secure, TAN-based payment system works with all checking accounts and is independent from the transmission technology (barcode, QR code, bluetooth).
Bluecode started in 2017 in Austria. Since 2018, Alipay users have also been benefiting from a cooperation between Bluecode and Alipay. The expansion into the German market took place in the same year.
How do customers link Bluecode to their bank account?
With Bluecode there are two ways app users can link their bank account:
With partner banks, they can register immediately and directly in their bank’s app or online banking. This registration is particularly fast and possible at all Bluecode partner banks.
At all other banks, you can register using a SEPA direct debit procedure. The direct debit mandate is stored and the payment processed by SIX Payment Services Ltd. SIX is a company audited by the Financial Market Authority and one of the largest direct debit processors in the German-speaking countries.
Are there payment limits when paying with Bluecode?
For security reasons Bluecode limits the number of payments to four payments per hour and ten payments per day with a transaction limit of 400€. This may vary depending on the issuer.
How does the Bluecode QR code payment work?
Bluecode QR Code Payment is a variant of eCommerce Payment. The checkout system (merchant's shop) produces a QR Code according to the payment data by calling a Bluecode API via Paygate, and then the customer scans the QR Code with his mobile device to finish the payment.

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 an Bluecode payment and 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 an their specialities:

Important notes when switching to live payments
Computop itself has a certified Bluecode implementation. However, when switching from test to production mode a merchant has to ensure:
- Use Computop URL "Bluecode.aspx" to initiate a Bluecode payment with redirect to Bluecode page containing the QR code
- Use Computop URL "BluecodeS2S.aspx" to retrieve a Bluecode URL which has to be transformed into a QR code by the merchant system
- Values for request parameter "RefNr" are unique per payment process – duplicate values will be rejected
- Values from response parameter "TransactionID" must be printed on customer's invoice / receipt
- Values from response parameter "TransID" must be printed on customer's invoice / receipt if not empty
