Visa Inc. and DeviceFidelity, Inc. are working to allow Apple iPhoneTM users to make payments by simply waving their iPhone in front of a contactless payment terminal. New technology combines a protective iPhone case with a secure memory card that hosts Visa's contactless payment application, called Visa payWave. Users will be able to make Visa mobile payments using an iPhone in retail stores, at fast food restaurants, in taxis, during sporting events (such as at baseball games), and also make purchases at vending machines that have contactless payment terminals. Thousands of merchants throughout the U.S. have already upgraded their payment terminals to allow consumers to make Visa mobile payments. The technology will also work with a majority of smart phones that have a slot for a memory card.
