    Nearfield (NFC) was supposed to do this. I was supposed to be able to fill a cart and just push it out the store and be charged.

        Well, it’s not NFC but Amazon has some convenience stores that can do it, I think there’s a limit on the number of items though.

        I can just imagine a shopping cart full of NFC transceivers screaming out there serial numbers simultaneously.
