The new gas station near my house does contactless. I think that now that the credit card networks are pushing liability onto the merchants we will start to see more and more of these popping up.
Heh unfortunately gas station pumps are exempt from the immediate liability shift and get an extension (https://usa.visa.com/visa-everywhere/security/emv-at-the-pum...) which means this will be a prime attack vector as the shift changes over the next few years.
