Scan QR Code

Zastrpay is generating standard QR Codes which can be read by any device implementing the QR Code standard.

An example of a Zastrpay QR Code can be found below:

ZASTRPAY:V1/T:TI/ID:3B6FDD92-E5E8-432E-AE47-1FFCF3104AE6/DIR:W

The format is based on the following rules:

• Key–value pairs are separated by /
• Each key and value is separated by :
• The code always starts with ZASTRPAY - this is also the first key-value pair. The value is the version number (e.g. V1) and indicates the format version for possible future extensions
• T indicates the type of data/QR code. Only TI meaning "Transaction Intent" is available for direct integration for the time being

The key-value pairs available for Zastrpay QR Code V1 and type TI are listed below:

Key	Value	Description	Example
ID	UUID/GUID with upper-case letters and hyphens	The UUID/GUID id of the transaction intent	3B6FDD92-E5E8-432E-AE47-1FFCF3104AE6
DIR	D for deposit (customer hands over cash) or W for withdrawal (customer receives cash)	The direction of the transaction intent	D

note

Zastrpay may add additional key-values to the QR Code, so the parsing of the string should be performed in a generic way accommodating for new key-value pairs, and different order. Only ZASTRPAY and T key-values are guaranteed to be at the beginning of the string.
