Hi,

The zxing barcode scanner on Android can be launched with a custom URL protocol which would allow you to use an Android phone as the scanner: https://stackoverflow.com/questions/13347145/android-barcode-scanner-integration-with-web-page

Another possibility is to print QR codes with a custom URL that goes to a .local hostname, allowing any phone to talk to a local Pi on the network.

Both require some network level access, either through Zeroconf .local domains or perhaps via a publicly accessible hostname.

The .local method would be useful if you have a "public wifi" that people can use, or just setup the Pi as an AP and allow people to connect to it for this purpose. That's probably the most robust solution for passers by. If this is used in-home then the .local solution on your home network is sufficient.

Could be a way to take it even further in a future project if you wanted to learn more. You could train the model on the libretro/retroarch cover art images available online. Just a thought.
