Cellphones may replace the need to carry a wallet

MULTI-PURPOSE Mobile phones are already used for many purposes and soon, following Asia's lead, Americans may be able to use them to buy goods

NY TIMES NEWS SERVICE , NEW YORK

People already use their cellphones to read e-mail messages, take pictures and play video games. Before long, they may use them in place of their wallets.

By embedding in the cellphone a computer chip or other type of memory device, a phone can double as a credit card. The chip performs the same function as the magnetic strip on the back of a credit card, storing account information and other data necessary to make a purchase.

In Asia, phone makers are already selling phones that users can swipe against credit or debit card readers, in much the same way they would swipe plastic credit cards. Trials are now under way to bring the technology to America, industry executives said.

Ron Brown, executive director of the Infrared Data Association, a trade group representing companies pushing the technology for cellphone credit cards, said that the new handsets could become "a major form of payment, because cellphones are the most ubiquitous device in the world." He added, though, that "cash will never go away."

Advocates say that consumers will readily embrace the technology as a way to pay for even small purchases, because it is less bother than taking a credit card out of a purse or parting with cash.

The impending changes to the cellphone happen to coincide with major shifts in the banking industry. Since credit cards are still considered somewhat inconvenient, particularly for quick, small purchases, major credit card companies have developed "contactless payment" technologies for checkout counters that allow customers to wave their cards near an electronic reader without having to swipe the card or sign their name.

MasterCard, for example, has introduced a system called PayPass that lets cardholders wave a card in front of a reader to initiate a payment, much as motorists use similar systems to pay tolls and the way some ExxonMobil customers use SpeedPass to buy gas. Several major credit card companies issue PayPass cards; McDonald's has agreed to accept them at some restaurants.

American Express announced late last year that it would have its system, ExpressPay, in more than 5,000 CVS drugstores by the middle of this year. Judy Tenzer, a spokeswoman for American Express, said the technology made it more likely that customers would use credit cards to pay for small items.

Cellphone makers are hoping these new payment systems will also make it easier to market handsets with credit-card functions, although they could just as easily represent competition for the practice of paying by cellphone.

The marriage of cellphone and charge card poses some significant challenges, including security problems. To reduce fraud from stolen phones, consumers may be required to punch an authorization code into their phone each time a charge is made.

For more than a year, phone makers, software companies and computer chip manufacturers have been working to develop secure and reliable payment technology for cellphones. After the phone's chip is recognized by the electronic reader, the credit card account number will be verified, as it is now, and the price of the purchase will be added to the consumer's credit card bill.

The new phones may also be capable of being programmed for a prepaid sum from which payments could be deducted.
