I'm anxious for a more secure version of RFID. I want to skip the checkout line altogether. Just walking through the door would read your ATM card, scan all of your groceriens and debit the correct amount. I'm sure that there will be some growing pains as there will be items that are not included in the scan, or pricing errors just like there currently are, but over all it should be faster.

with this kind of system, how do you choose the method of payment? sometimes i use my debit card account; sometimes i'll want to use any number of CCs in my wallet. do you pre-register? does that limit flexibility if you do? and given that i do monitor the scanned price, it'd seem like a hassle to verify and correct pricing errors, as you note.
