Forget your credit card - pay with your watch

We are so behind the technological curve here in the U.S.

All over the world, people buy stuff and use their cellphones to pay.

Now Casio's upped the ante with their G-Shock GWS-900.

It does what a transactional cellphone does, except it's been squashed down into a watch.

Also tells time, waterproof, solar-powered, you know, the usual Casio drill.

How much?
