Sprint has been the only carrier so far to officially support Google’s own Wallet NFC payment system as the other carriers have been banking on another mobile payment system called ISIS. Now after tedious months of uncertain waiting, it’s been reported that ISIS may finally launch this September. This report comes from Bloomberg who interviewed the CEO of VeriFone, a company that makes payment terminals, who said that the initial launch is set to take place in September in the lovely cities of Austin, TX and Salt Lake City, UT. Unsurprisingly, ISIS refused to anything more than a launch coming this summer and neither AT&T or Verizon would open up when pressed.

We’re sincerely hoping that this time the service will actually launch as it’s been delayed more than once now. If it does launch, it should provide a nice alternative to Google Wallet for those on carriers that don’t support Wallet. Let us know if you’re excited for this new NFC payment service.

MasterCard has just announced all the devices that will be eligible for the ISIS service. Devices on the US carriers are:

Verizon: HTC DROID Incredible 4G LTE, Samsung Galaxy S III

AT&T: HTC One X, Samsung Galaxy S III

T-Mobile: HTC Amaze 4G, Samsung Galaxy S III, Samsung Galaxy S II
