Cards are moving towards no card at all i.e. virtual cards. USA is very slow in adopting new payment technology compared to the rest of the world. I live in South Africa and tap to pay is so much of a thing that you do not have to worry if you leave your card at home as you can tap at like 80% of the merchants, and if you can't they will have a fall back like QR code etc, NFC enabled cards have been around for years and all the merchants are really quick in adopting them.
