     Which are you more likely to have with you at any given moment-your cell phone or your wallet? Soon

you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over

an electronic scanner.

     In January, Starbucks announced that customers could start using their phones to buy coffee in 6,800

of its states. This is the first pay-by-phone practice in the U.S., but we're likely to see more wireless payment

alternatives as something called near field communication (NFC) gets into America's consumer electronics.

Last December some new smart phones which contain an NFC chip were introduced to the public.

     Already in use in parts of Asia and Europe, NFC allows shoppers to wave their phones a few inches above

a payment terminal-a contact-free system built for speed and convenience. But before NFC becomes widely

adopted in the U.S., a few problems need to be worked out, like who will get to collect the profitable transaction

(交易) fees. Although some credit card providers have been experimenting with wave-and-pay systems that

use NFC-enabled credit cards, cell phone service providers may try to muscle their way into the point-of-sale

(POS) market. Three big cell phone service providers have formed a joint venture (合资企业) that will go into

operation over the next 15 months. Its goal is "to lead the U.S. payments industry from cards to mobile

phones."

     The other big NFC issue, apart from how payments will be processed, is security, for instance, what's to

stop a thief from digitally pick-pocketing you? "We're still not at the point where an attacker can just brush

against you in a crowd and steal all the money out of your phone," says Jimmy Shah, a mobile-security

researcher." Users may also be able to set transaction limits, perhaps requiring a password to be entered for

larger purchases.

     Still uneasy about this digital-wallet business? Keep in mind that if you lose your smart phone, it can be

located on a map and remotely disabled. Plus, your phone can be password protected, your wallet isn't.
