It didn't take long for Visa to react to the three-headed beast of AT&T, T-Mobile and Verizon entering the mobile payments arena. The world's foremost payment processing company has just announced that it's about to start a trial of its contactless payment system in partnership with Bank of America. Kicking off in the New York area this September and lasting through the end of the year, the scheme will most likely involve the MicroSD NFC communicator and In2Pay iPhone case that DeviceFidelity has been developing for Visa. No disclosures are being made on the size of this pilot scheme, though we're told that only a "select" group of employees and customers will be getting the mobile payment chips. Don't worry if you miss out on this one, though, as a similar trial is scheduled to begin in October with US Bancorp. That should give you enough time to turn yourself into a high-rolling select customer, right?
