Visa teams with DeviceFidelity for contactless payments via microSD card
Visa has been working on contactless (a.k.a. NFC) payments for quite some time, and it's now teamed up with DeviceFidelity in the hope of bringing them to even more cellphone users. That company makes (among other things) a contactless payment system contained on a microSD card which, when paired with Visa's own payWave system, will let you use just about any microSD card slot-equipped cellphone to make pay contactless payments at between 50,000 to 60,000 merchants in the US. Exact specifics are otherwise a bit light, but Visa says trials are scheduled to begin in the second quarter of this year.
