Using Your Cell Phone as a Credit Card.

The New York Times has an interesting article about including credit card information within your cell phone. Not only would it save your credit card information, but it can be used as your credit card.

I know that cell phones are increasingly providing more and more functionality. Not content with making phone calls and keeping address books, devices like the Treo 650 also include the ability to send text messages, access the web and your email, organizers, and cameras.

In Asia, phones are already being made and used as credit cards. Vivotech is one such phone. You can see one way it works on their web site. Basically, at the time you would normally provide cash, write a check, or provide a credit card to pay for a purchase, you move your cell phone close to their access point. The transaction finishes, providing you with a digital receipt.

Although not yet available in the United States, this is very popular in Asia. I’m pretty sure I won’t be one of the first to buy one when it comes here, though. I’d be too afraid of losing the phone and then . . . it just makes me nervous.
