Cell phone as a wallet....

[KarlMarx]

Consumers can already pay for merchandise using their cell phones in South Korea and Japan, and they'll be able to do it in the U.S. in 18 months. Many of the phones have been integrated with banking systems so people already are buying groceries and soft drinks from vending machines with them. Wallet phones are not just used as credit cards—they can contain entrance tickets, metro tickets, loyalty cards, air tickets, and employee ID cards, according to SmartTrust's recently published "Mobile Trends" guide. In fact, earlier this month Motorola unveiled its M-Wallet product, which will let people make purchases using their cell phones. Securing mobile devices will become even more crucial, such as making sure that devices have the proper virus software. (InformationWeek http://www.informationweek.com 02/17/06)
