Ah cool. I kinda wish that card issuers would issue a tiny little NFC disc or something so I can just integrate that into whatever and get the same functionality.
But that’d probably be a thing all of 8 people on earth want, and everyone else would lose it or eat it or something.
Costco has something like that for gas only (e.g. so your teen driver doesn’t need the card).
Just give me the NFC bit and let me set a low limit on it, and I’ll tape it to a Casio watch or something, I just need something I can wear and buy stuff with. Make it water proof so I can take it swimming too.
I mean, this is really janky, but you can probably get a second credit card and just cut it down. The NFC area on a credit card is quite small compared to the card itself. I doubt anyone would question it if you were tapping “something” on your wrist to a terminal as people are now used to smartwatch payments.
OK, so I followed up on this idea and I’m not sure how viable it is. The chip is very small, but the antenna is quite often traced quite far across the card. The layout depends on the card, but might be more of a pain than it’s worth.

Lol, that’s actually genius, maybe I’ll try it with a card I don’t use much.

Dang. I guess I’ll keep my current method for now. Thanks for the update!
