Parses information in ticket aztec codes according to UIC 918-3

Parses online tickets for trains following UIC 918-3 and checks the signature

Dependencies

sudo apt install kaitai-struct-compiler

Usage

1. Run bootstrap.sh to setup the environment (python requiements, generate models, downlad keys)
2. Scan the aztec code of the online ticket e.g. using your phone and write the binary data into a file
3. Run python examples/parse.py examples/ticket-visible-in-a-movie-scene

Example

The example directory contains a file that was extracted from a ticket that was once visible in a movie scene and probably contains fake data. This is the output of this script:
