    What exactly does the bar code encode? I suppose it must be the unique identifier of the receipt. Can you look it up on the web? Or is it only useful to the employees of the store?

      You have to scan it to exit the selfcheckout and the store. If you use the manned checkout, you do not need to scan anything to exit

      Assuming that the Norwegian system is in anyway similar to the Finnish system I use, they just print the system id and the n:th of you on a piece of receipt while the system just checks that no similar register/customer id’s have passed.

      We tested this with friends where multiple friends bought stuff from the same register, but exited using only a single one and they were usable afterwards, but only once per.
