There's a company called Mobilelime doing this in the Boston area. I've used it a couple of times and have to say it's pretty easy and seems secure. You have to enter a PIN to complete the transaction, then you get a receipt tm'd to your phone.
There aren't a lot of shops to use it at (although one IS a liquor store) right now, but if more people try it I'm sure it'll catch on.
