i should've been clearer: while browsing i found multiple apps that do this. most use AI to extract data from images and are much more feature-rich - you can photo your boarding pass and it goes straight to wallet. however, i noticed that AI sometimes gets details wrong. for example, when i uploaded just a barcode image, it couldn't create the pass because the model also wanted a "name" field.
Could you add Codabar?
edit: oh, I guess you can't, because Apple Wallet doesn't support it.
When I’ve done similar things in the past I found there was always a library for barcode/QR use cases before such things ended up being built into the OS/Framework I’m in.
https://serratus.github.io/quaggaJS/ seems browser friendly?
Generally I agree with your point on AI fuzziness here not being useful.
