That’s actually pretty easy. And a month ago I asked nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 about the NFC part, technically any NFC would work exactly like the card you have. They sell them dirt cheap on Amazon. I have a bag of these. You can color them Orange, put a Bitcoin logo on it and you got your self Bitcoin-coins?
