The Central Bank of the Republic of Turkey (CBRT) has published a guide containing the detailed technical principles and rules for using TR Karekod in transactions carried out through card payments.
The guide was prepared on the basis of the Regulation on Generating and Using TR Karekod in Payment Services (the Regulation) and the TR Karekod Principles and Rules document (the Technical Document), and it aims to define the specifications for arranging the QR code structure to be used in card payments in line with the Regulation and the Technical Document.
V1.1 defines new flows required for transactions to be made with the QR code when the card issuing institution and the institution providing the mobile application service are different. In this context, the guide includes the workflows of QR code usage models for various card payments.
The guide can be accessed at the link below:
What does the guide define?
The guide defines which fields the QR code used in card payments will carry, how those fields will be formatted and in which scenarios it will be used. This way, codes generated by different banks and applications are compatible with one another.
The guide also covers cases where the institution issuing the card and the institution providing the mobile application are different, because in this scenario information must be transferred securely between the two institutions.
For developers, the guide can be used as a reference document in integration testing.
