Your Next Wallet Is Calling
"Contactless" hardware lets phones and gadgets pay with a tap, but the coming plethora of apps that use it may confuse users.
Soon you'll be able to pay for goods in U.S. stores simply by waving a cell phone over a reader, or connect with other gadgets by tapping a phone against them.
But there's a catch. Although new near-field communication (NFC) wireless chips will make it possible for gadgets with the technology to work with each other, the software applications being developed for these devices may not play so nicely together, making it potentially confusing for users.
Last week, Google CEO Eric Schmidt announced that the next version of the Android operating system for smart phones will support NFC technology. Such phones would also be able to transfer information—a credit card number or contact info, for instance—over a short distance. Nokia has said that most of the smart phones it releases next year will also feature the technology.
The technology is already common in Japan, and has been under development elsewhere for years. In the U.S., banks and payment networks like Visa and Mastercard have over the past five years handed out credit cards and key fobs that can be waved over a reader in a store to pay for goods or services.
