I saw this technology and posted about it 4 years ago now its here! Which makes it the perfect time (holidays), and place (amazon) to try out this awesome technology that will make your wallet be slimmer! Would make a great gift for just about anybody who has a fat wallet.
Got the coin, added several cards. Most of them are EMV chipped cards so... Coin does NOT work on EMV terminals without the NFC payment option.
Gas stations - 2 tested (one was a bit tight, but worked)
Bed Bath and Beyond (cashier was a little confused when asked to check card)
All EMV terminals so far that require card to be inserted.
