Noticed this on Fdroid recently, it has a really nice UI and auto generates real barcodes from images. Their document scanner app is pretty nice too. It seems like early development so I’m excited to see it improve from here!
I use Catima and I am happy with it but it doesn’t have the feature to crop images and use it as a logo. It’s easy enough to image search logos though.
I might give this a try. I use Google Wallet for my various loyalty cards and whatnot, but it is actually a poor UI for it, mixing credit cards and loyalty cards in a single sideway sliding interface that takes forever to find what you want.
It definitely is useful, I use it for train tickets, or user QR codes for things such as IKEA, supermarkets, gas stations… It’s quite literally a virtual wallet where you have all your “cards”, but they are QRs.
This way, for example, you don’t have to install every single app to get the QR code that identifies you in every market. You just paste them into this wallet and you are good to go!
NFC payments require a transaction platform and these things are only possible with banks or huge, “trusted” companies like Google/Apple.
Although things might start changing in Europe (for now) with GNU Taler.
NFC payments are NOT happening in FOSS I’m afraid. No bank will expose their APIs for it, and any FOSS app dealing with payments might get sued pretty fast.
