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.
