Have any of you heard of the new technology in Japan that's letting people pay for everything with their cell phone. It's pretty awesome! Check it out: http://www.usatoday.com/money/economy/2008-08-19-759131637_x.htm This is pretty neat stuff. I wonder how long it will be before that comes here.
I see they're being used for primarily small purchases, but it would have to be linked to some sort of account where you kept money. I wouldn't trust it personally. I'll use my phone for most things but I see no reason to have any sort of financial information of mine being bounced around like that.
