The result is that once you've grabbed your groceries and put them into your bag, you simply walk out of the place—no lines, no cash registers, the bill goes straight to your Amazon account.
The credit card, dubbed Motion Code, contains a small display in the reverse of the card across the signature strip which randomly generates the card's new security code -- the card verification value (CVV) -- every hour, according to The Memo, which spoke to the company, Oberthur Technologies.
