Like 3D on high-end HDTVs, NFC-based payment systems seem set to invade our mobile lives whether we like them or not. Isis, a collaborative venture between AT&T, T-Mobile, Verizon and a bunch of banking big timers, has today announced the first market for its rollout of a contactless payment scheme, and it’s none other than Salt Lake City, Utah. That’ll surely raise eyebrows in locales that may consider themselves more tech-savvy, but we reckon starting off with a city of a smaller scale might be good for getting this “mobile wallet” system off the ground. And then there’s the added benefit of Isis snagging a deal to enable compatibility with the entire Utah Transit Authority footprint. If all plans are executed properly, that should mean that by summer 2012 the good people of SLC will be able to NFC their way around town with just their smartphone in hand, while also swiping it through checkouts like some form of highly advanced techno-humans.
