This document, created in line with the Regulation and the TR QR Code Principles and Rules document annexed to it, provides sample mobile payment workflows suited to the merchant-presented and consumer-presented QR code usage models and defines the TR QR Code data organization for mobile payments for both usage models.
Within the scope of the principles and rules in this document, the definitions in the TR QR Code Principles and Rules document are used for the features of QR code technology, the encoding of data objects, data types and formats, the QR code data organization according to the business model used, and the properties of data objects.
This document has been prepared on the basis of the first paragraph of Article 6 of the Regulation.
The guide can be accessed from the link below:
Two usage models
If the user scans the QR code displayed by the merchant, this is called the merchant-presented model. If the user displays a code in their own app and the merchant scans it, this is the consumer-presented model.
The guide defines how data is organized in both models, which fields are mandatory and which formats are used. This way, different apps read the same information from the same code.
Teams developing payment apps should test the flows for both models.
