Google Wallet works EVERYWHERE, because it just emulates a Visa card.
You misspelt nowhere, but yeah everywhere/nowhere the keys are right next to each other.
Here's a fun fact. Google wallet actually works as you describe it. It emulates a card. It also works on pretty much any NFC terminal. It's just a shame that it is actually supported in VERY FEW COUNTRIES. Yep, despite looking like a generic VISA card Google Wallet is geo-locked and won't even appear in the Play Store in many parts of the world. Hence companies have gone and done their own thing. Hence my comment about fragmentation.
You can talk it all up as much as you want, but until it works without having to root the phone and side-load the application my original comment still stands, this is a good marketing move by Apple, and Google and the Android eco-system are so fragmented that they are effectively being bypassed by banks who are getting sick of this mobile shit (as mentioned in another comment some banks here offer NFC stickers people can glue to their phones to get around the solution that really doesn't at all work "everywhere").
