NFC on the phone.

I thought it would revolutionise lots of things. Turns out it took 10 years longer than I expected and is just a "fun" feature for now.

NFC & Android/Apple Pay is actually kinda amazing if you live in a country like Australia where tap to pay is universally supported. It's starting to get traction for transport smart cards as well.
