So what are we waiting for in the rest of the world? If it can be done in Japan, why not here...?
"Japan's NTT DoCoMo said Wednesday that, since July, it has sold one million phones that can be used to make payments. 'The phones use built-in smartcards that enable users to swipe the devices near point-of-sale terminals to pay for purchases. The wireless carrier launched the service last summer and there are about 13,000 shops and 2700 vending machines in Japan that accept that sort of payment."
