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.
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.
Millions of barcodes are scanned every second, and has been for the past few decades. So it seems very strange that there aren't any solution readily able for your app, which isn't AI.
I have to scan bar codes every once in a while with an app on my iPhone, which definitely doesn't use AI. It will instantly recognize a bar code before I've had a chance to line up the camera properly, and the error rate is zero.
Try Pass4Wallet from the app store. It's free and supports a huge array of barcode types, including codabar. It's been my go-to custom card app for a number of years.
