KDE PIM/KItinerary/Trenitalia Barcode
< KDE PIM | KItinerary
General Observations
- always 67 bytes
- exactly for one passenger/leg
- does not seem to contain signatures, checksums or compression, based on minimal bit pattern changes on adjacent tickets
- a lot less null bytes when PNR/seat reservation are present (ie. highspeed train tickets?)
