Isis, a joint venture of AT&T Inc., T-Mobile USA and Verizon Wireless, announced Tuesday that it's working with gasoline fuel dispenser makers Wayne and Gilbarco Veeder-Root.

Both will soon start using Isis' mobile commerce application SmartTap, which will allow consumers to make mobile payments and redeem offers after tapping their phones. Each will begin rolling out the feature at locations in Isis' testing grounds in Austin and Salt Lake City.

"The gas pump is one of the most frequented point-of-sale environments, and a critically important addition to the mobile commerce marketplace," says Scott Mulloy, Isis' chief technology officer, in a press release.

Wayne is a unit of GE Energy. Gilbarco is a subsidiary of the Danaher Corp.
