Its a great step for NFC adoption in the US but permit me to brag a little by showing you the NFC-payment system in Hong Kong (Octopus Card) which you can use in:
- all public transport (subway, bus, tram, ferry, etc)
- shops (7-11, drugstore etc)
- as access card to buildings, offices, residence
... and on a run-down boat which charges you HK$1.80 per ride (US$0.23). This is the ultimate Mom and Pop shop.
