Isis, the mobile commerce joint venture between AT&T Mobility, T-Mobile USA and Verizon Wireless, announced it will conduct a pilot of the Isis mobile commerce program in Salt Lake City in early- to mid-2012.

Isis has also entered into an agreement with Utah Transit Authority (UTA) to make the entire UTA transit system Isis-enabled, marking the deployment of Isis as the first commercially available mobile transportation fare payment program in the U.S.

The joint venture is also investing in the necessary infrastructure to enable mobile commerce on a nationwide basis and will be available to all merchants, banks, payment networks and mobile carriers.

“By working with the Utah Transit Authority, Salt Lake Chamber and Salt Lake City-area merchants, Isis is bringing the mobile commerce vision to reality. Salt Lake City consumers will experience a new way to shop, pay and save,” said Michael Abbott, chief executive officer at Isis, in a statement.

The formation of Isis was announced in mid-November 2010. Its aim in Salt Lake City is to bring mobile commerce to the city by using mobile phones to make point-of-sale purchases through the use of near-field communication (NFC) technology.

According to a press release, the system will evolve to offer customers a secure and convenient way to pay, redeem coupons and store merchant loyalty cards, by simply tapping their phone on a terminal or other enabled device.

The Isis mobile payment program will roll out in 2012.
