The paypass sticker uses NFC. The benefit of using an in-phone chip with a wallet app is potentially increased functionality over a simple sticker. Balance checks, etc on your phone. Plus you can pay for larger puchases - you can potentially enter your pin for larger purchases. I believe CIBC, RBC, and TD all now have mobile wallets based on NFC. Tim Hortons has an NFC-based payment app also that replaces tim cards. It is out of touch to say NFC is not in use - it is here in Canada, and uptake on mobile wallets is happening. However, NFC is not pervasive in the US, and we'll have to wait and see how they go. The real driver is what technology gets rolled out as POS terminals. Canada is well into having NFC almost everywhere, so the mobile wallets based on NFC followed.
