It would be nice to have a way to import such tickets via a photo or the barcode text read via other means. There is an article (in french) about them and other on https://zestedesavoir.com/articles/3625/anatomie-dun-titre-de-transport-du-billet-a-la-carte-a-puce/#1-le-billet-cartonne-classique They should be IATA-compatible, the norm they follow is available at https://www.era.europa.eu/sites/default/files/filesystem/tap/baseline_1.2.0_archive/era_technical_document_tap_b_6_v1.2.pdf The ZXing library implements PDF417 decoding from pictures, it could be used as an example, I don't know if libre C++ libraries exist: https://github.com/zxing/zxing Interesting material, this seems to be yet another type of barcode used by SNCF. I can only decode the first two, zxing both on my workstation and on my phone fails on the third one unfortunately. The first two contain a 171 byte binary payload in base64 encoding, which doesn't match the ERA SSB binary formats nor the ERA ELB format observed in TGV tickets (see also https://community.kde.org/KDE_PIM/KItinerary/SNCF_Barcodes). The latter is what the documents you linked to refer to as well, and which we already have support for. So supporting this format depends mostly on either finding documentation about it, or getting a lot more samples hoping we can reverse-engineer it from those. That's a lot of work though, with no guarantee of success. |
