Is there another way to reading QR codes on a phone?
Cool nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj hack for iOS:
You can redeem a token with just the QR code by saving the image to your gallery and then long-pressing on the image to open it with the app!

Discussion
There are apps that can do it, or you can upload them to QR-decoding websites.
Photo app seems faster. I wish this can be implemented inside apps.
