I seriously doubt NFC will matter anywhere other than US very much.
We have tons of NFC-enabled terminals in Italy, at least in the bigger cities. They're already used by Mastercard PayPass and Visa PayWave. If I could use my Italian credit card with Google Wallet (or even recharge the Google prepaid card) I would be doing half of my purchases via NFC.
Really? Very interesting.
It could matter if it was supported in software and ecosystem, which it more than likely won't :(. We have a lot of NFC terminals in Canada and I wouldn't mind ditching a few paypass/paywave cards from my pocket but it won't be that simple.
