Visa, MasterCard, Discover and American Express Join Isis

This morning at the annual Fortune Brainstorm TECH conference in Aspen, Colorado, Isis – the national mobile commerce joint venture between AT&T Mobility, T-Mobile USA and Verizon Wireless – announced that Visa, MasterCard, Discover and American Express will join Isis.

With the stated goal of making mobile commerce a reality for millions of US consumers and merchants. Isis officials say that its relationships with all four payment networks means that “with Isis-enabled phones and payment terminals in place, merchants and consumers will have ubiquity and freedom of choice when it comes to payment network acceptance.”

Today’s announcement underscores Isis’ inclusive approach, providing all critical stakeholders – banks, merchants and consumers – with the freedom and choice necessary to foster a robust new industry and make mobile commerce a reality.

“Since the formation of Isis in November, we have been committed to building a mobile commerce platform that aligns and advances the interests of consumers, merchants and banks,” says Michael Abbott, chief executive officer for Isis. “By working with the nation’s payment networks – Visa, MasterCard, Discover and American Express – we significantly advance the vision of an open and secure platform that provides banks and merchants with a new and highly relevant way to connect with consumers.”

Earlier this year, Isis announced Salt Lake City, Utah and Austin, Texas as initial launch markets, slated to roll out in the first half of 2012 with support from all four payment networks.
