PayPal Mobile is currently only available to eBay employees, but it can be the next good killer application. Imagine the convenience you can make a purchase from a mail order magazine by just sending a text message ... without all the hassle of filling and mailing a form. You don't even have to provide (or memorize) your shipping address.

PayPal is going mobile.

The online payments giant is gearing up to launch a service that would allow its customers to make purchases or money transfers using simple text messaging on their mobile phones.

...

"Buy it when you see it. Where you see 'Text to Buy' -- on a poster, in a magazine, at an event -- just order the item securely by text message," PayPal says in the promotional materials on its Web site .

For example, customers might see: "To order this DVD, text 'DVD to 63336.'" Immediately after the customer does this, PayPal calls the customer back to confirm the order and asks the person to enter his/her PayPal Mobile PIN. Once the customer confirms, the item is shipped to the home address listed on the user's PayPal account.

Just like the traditional PayPal service, PayPal Mobile makes it free to send money, though wireless carriers may charge fees for receiving text messages. If a call is dropped before payment details are complete, the user can send it again without worrying about paying twice, PayPal said. No money is sent until the user fully confirms.
