Abstract: The invention relates to a store arrangement for purchasing articles in a self-service store according to a self-registration system whereby a client himself registers articles selected by him with a scanner. The store arrangement includes at least one identification device for recognizing a client and a readout station for reading out the articles registered with the scanner. The store arrangement further comprises a paying station for paying in electronic manner and without intervention of store personnel for articles read from the scanner by the readout station, and for clearing a passage for the client to leave the store when the articles have been paid for in electronic manner.

Abstract: A customer pass or card registered in the client's name is issued to each client who wishes to make use of the self-registration system. A check parameter, such as an integer, is assigned to the customer pass, and is either recorded in the customer pass or stored in the memory of a computer. After the client has registered the selected articles using a portable scanning device, the scanner is coupled to a readout station and at the same time the identity of the client and the associated check parameter are determined. With the aid of an automatic device, such as a random number generator, it is determined whether a spot check should take place. The store arrangement includes shelves 3, typical cash desks 4, and a check selection station 22 where a client wishing to make use of the self-registration system presents the customer pass. Station 22 determines whether the client must be spot checked.
