Parses the Aztec code data of a Deutschlandticket. It is only a dumb parser so far. It doesn't do any signature verification or further processing. Feel free to add this functionality with a pull request.
I recommend Binary Eye for the first two steps.
- Scan your Deutschlandticket Aztec code, e.g., by making a screenshot and scanning it with a Aztec code scanner capable of doing so from an image file.
- Store the data in a file called 'aztec.bin'
- Copy this file into the main directory of this repository
- Execute
python3 main.py
The Deutschlandticket Aztec code is distributed as a VDV-barcode defined in the VDV-Kernapplikation (VDV-KA). See: https://docplayer.org/61642532-Spezifikation-statischer-berechtigungen-fuer-2d-barcode-tickets.html Section 4.3
The Deutsche Bahn (DB) usually uses the UIC standard for their distribution of tickets. However, they start to integrate the VDV-KA standard as well, e.g., for Schönes-Wochenende-Ticket, Quer-Durchs-Land-Ticket, Länder-Tickets, City-Ticket, and City-mobil. And apparently now for the Deutschlandticket as well. See Interoperabilität Barcode DB Online-Ticket VDV-KA for more information about the compatibility between the UIC and the VDV-KA standard. In a nutshell, they use the same Aztec 2D-barcode representation, but after scanning the ticket it needs to be processed differently.
