It would be great to have a barcode scanner to save cards within the wallet. Stored cards can then show the corresponding bar code when needed.
I can also recommend the open source loyality app "catima" which does exactly that.

I hate Bitcoin and cryptocurrency in general! And I don't want to put my bank accounts or credit cards in a digital wallet! All I want is a Google-like wallet -- WITHOUT creepy, invasive Google -- to better maintain my privacy and security.

please, search the internet, use https://catima.app/ for example for loyalty cards, and regarding apple pay and gpay, drop those off and use your standard, normal plastic nfc cards, you really are not forced to use those "apps" in order to pay everywhere. (Phisical money also exists!!)

Also, you don't need to store EVERYTHING on your proton account, that's a single point of failure.

That's a great idea! Having a unified app to store all those cards would be super convenient and save a lot of hassle. While there are apps that let you store loyalty cards, integrating official documents like a driver's license or professional cards would require high-level security measures.

On a related note, I've recently come across https://paykassma.partners/, a platform that specializes in optimizing processes, including secure data handling for businesses. Perhaps a similar solution could be used or adapted for personal card storage, ensuring both efficiency and top-tier security. It's worth exploring!

This may be added to Proton Pass instead

No, wallet is wallet and loyalty cards are other thing, you are merging two difference concepts here, maybe a diferent app for keeping those cards like https://catima.app/ or just adapt a fork of catima and integrate it into the Proton ecosystem, but keep wallet just for money

Yeah Proton, we could get rid of Google pay and use Proton Wallet (Or Proton Pay) which could allow to pay with Bitcoins or with my credit card.

That would be great to get rid of Google pay app that i use to store loyalty cards with barcodes

that would be cool! there's an app called catima out there for non-NFC cards
