US EMV transition could open door to more NFC mobile payments

The clock continues to tick on the EMV liability shift in the U.S. Merchants have six months left to upgrade their point-of-sale terminals to accept the chip cards banks are issuing to their customers.

Walmart's Mike Cook recently called the current transition a joke, mostly because the card brands insist on chip-and-signature to verify transactions instead of the more secure chip-and-PIN method, which is the standard in most countries including Canada and the U.K.
