Is it possible to use an nfc card to pay LN invoices? I feel like that might be necessary for mass adoption
Discussion
Necessarily you have to have a "hot wallet" to have a lightning wallet. I am not sure of the question exactly, like can an NFC card copy and paste a Lightning invoice? Because you preload NFC cards with information and the purchaser is the one receiving info, not giving it. The closest to this is an on-chain Satscard but that's not lightning.
I wonder if you could scan the card, and then the POS communicates with your wallet/node to pay the invoice on the POS. I don’t think it could be done today
I think there was something developing. 🤔
Look into LN bits, iirc they have everything on the LN side to make it work. Also a app to read/write to nfc cards is needed.
You also could use a nfc ring if you want to make it extra fancy😂
