Why? If you had those cards, or a smartphone with NFC and Google Wallet installed, you could do the same thing in the US. Just look for the MasterCard PayPass logo on the top of the terminal you are swiping your card in today.

I've seen it at CVS, RiteAid, McDonalds, Wawa, ShopRite, Home Depot...

We have vending machines with these at my university. I often start swiping my card only to realize I've accidentally "tapped to pay" (according to the reader).
