General Observation
- PDF contains a Code 128 1D code and a QR code
- The 1D code contains the ticket number (CP \d+), which is also printed under the QR code
- Both codes in the PDF are implemented as ungrouped individual rectangle paths, which currently failed to be recognized.
- The QR code contains a base64 encoded payload
- Content varies in size (87-89 after base64 decoding in the known samples)
- Content seems byte-aligned
- The content seems backwards!?
- The station codes used are listed as "IBNR" on https://www.bazakolejowa.pl/index.php?dzial=stacje&id=664 - and match what's in PKP tickets - but this isn't IBNR. Neither Wikidata nor Trainline have those codes.

| 14 | 1 | 0x00 | ||
| 15 | 12 | suspected to be 3 x 4 bytes of date/time values (issued/valid from/valid until?) | ||
| 27 | 2 | uint16 LE | departure station code | same ids found in PKP tickets, but not matching any so far known id schema |
| 29 | 2 | uint16 LE | arrival station code | |
| 31 | 10 | string | passenger name | given/family name separated by '.', given name truncated to fit, string in reverse order!? |
