me: "All LN wallets must support transactions via NFC (with unlocked phone of payer and pop-up confirmation window). Then it will be faster process than current hassle with scanning QR codes."
@Athena_Alpha: "Yup. Tap to pay is amazing and Bitcoin / Lightning solutions need to absolutely prioritise it more. QR should also always be displayed or available, but tapping is just so much quicker as it's the data transfer AND authorisation rolled into one action"
me: "of course, QR should also always be displayed or available (not all people have NFC in their phones). You simply have two options active simultaneously, and if you choose "tap to pay" - that's your decision (and comfort) only"
I think it should do both at the same time then it doesn't matter. NFC has only really gone mainstream in the last two years, many people still don't have devices with it, but it's practically a given if you get any new device since 2021.

I don't think there is any technical problem here if NFC tags are working fine with LN:

There is: wallet devs must implement the correct specs for that type of NFC payment. Is not just about to write a dumb LNURL-w on that NFC, is about some things more. https://github.com/boltcard/boltcard/blob/main/docs/SPEC.md
Right now only BoltCard Wallet, Breez and WoS have that implemented fully. All the rest still working on it.
