Domestic Ticket
General Observation
- Aztec barcode, in PDF or image
- Variable length
- For domestic tickets only, international ones use RCT2 in UIC 918.3 container
- zlib compressed textual payload starting at offset 3.
- zlib decompressed content is plain text and hardly larger than the full compressed data, which suggests the compressed data doesn't span the full length of the barcode (signature?).
Binary Structure
Offset | Format | Meaning | Notes |
---|---|---|---|
0 | 0x04 | ? | fixed value |
1-2 | 16 bit BE | ? | varies with length? |
3-4 | 0x78 0x9C | zlib marker | |
5+ | zlib | see below | |
? | ? | ? | high entropy data, signature? |
-16 | 0x00 | ? | last 16 bytes are always 0x00 |
Textual Payload Structure
- 32-34 lines, delimited by 0x0A
- if there are less than 32 lines, line 30 (and possibly 32 or 33) are omitted.
- strings are UTF-8 encoded
- date/time format: 8 digits, the first 4 digits are the days since 2009-01-01, the last four are the time in "hhmm" format. Local time/no timezone.
- class information is either provided as "[1|2].tr." ("trieda" is class) or "*" if there is no class.
