HTC, LG, Motorola Mobility, RIM, Samsung Mobile and Sony Ericsson will all introduce contactless-enabled devices that implement Isis' NFC and technology standards.

The venture - set up by AT&T, T-Mobile and Verizon Wireless - has also begun working with vendor DeviceFidelity to add NFC functionality to phones which do not have it inbuilt.

Isis was set up last year, as the telcos banded together in a bid to gain a slice of the rapidly expanding and competitive mobile payments market. In July they brought on board Visa, MasterCard, American Express and Discover.

The venture plans to roll out its service in Salt Lake City, Utah and Austin, Texas in the first half of next year before gradually spreading the offering nationwide.

Scott Mulloy, CTO, Isis, says: "Isis' technology standards provide the direction and certainty needed for the development and deployment of NFC devices and the mobile commerce ecosystem. Working together with the device makers and our founding mobile carriers, Isis can provide the consumer choice and scale necessary for widespread adoption of mobile commerce."
