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. If a spot check is needed, the client is directed to a check cash desk 24 where a storeworker registers the articles in the normal manner. If no spot check is needed, the client can go directly to the readout station 6 where the portable scanner is read out automatically.

Claims

1. A method for checking articles registered with a scanner by a client himself in a self-service store, wherein a customer pass registered in the client'"'"'s name is issued to each client who wishes to make use of the self-registration system;

a check parameter is assigned to the customer pass;

after the client has registered the selected articles, 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 by means of the customer pass; and

with the aid of an automatic device it is determined, starting from the check parameter, whether a check should take place.

2. A method according to claim 1, wherein the check parameter is an integer;

with the aid of the automatic device a random integer not greater than the check parameter is generated; and

a check is carried out if the generated number is equal to a predetermined number.

3. A method according to claim 2, wherein the check is carried out by a cash desk storeworker, who manually registers the selected articles, the result of this registration being compared in the readout unit with the result of the registration with the scanner, without the result of that comparison becoming observable by the cash desk storeworkers, and finally one single receipt is produced.

4. A method according to claim 3, wherein the check parameter is modified depending on the result of one or more checks.

5. A method according to claim 4, wherein a scanner is supplied to a client after identification through a customer pass.

6. A method according to claim 5, wherein the customer pass is a contactlessly readable card.

7. A method according to claim 6, wherein the information stored in the card is at least partly modifiable.

8. A method according to claim 7, wherein the check parameter is stored in the card or in a computer.

9. A method according to claim 8, wherein in a check selection station preceding the readout station the identity of the client and the associated check parameter is determined by means of the customer pass and subsequently it is automatically determined whether a check should be carried out;

and if a check is to be carried out, the client is guided to a check cash desk, where the articles selected by the client are registered once again by a storeworker, the result of that registration being fed to the readout station to which the check cash desk is coupled.

10. A store arrangement for practicing the method according to claim 1, comprising a readout station for reading out the articles registered with a scanner;

a device for recognizing a customer pass and means for automatically determining an associated check parameter, whilst further an automatically operating device is provided, which, depending on the check parameter determined, generates a signal indicating whether a check should take place.

11. A store arrangement according to claim 10, wherein the check parameter is an integer;

the automatically operating device, depending on the check parameter determined, generates a random integer not greater than the check parameter and produces a check signal if the random integer is equal to a predetermined number.

12. A store arrangement according to claim 11, comprising a dispensing station for portable scanners, this dispensing station comprising an automatic identification device for identifying a customer pass that is being presented, and this dispensing station releasing a scanner after recognition of a customer pass.

13. A store arrangement according to claim 12, wherein the readout station is adapted to produce a receipt.

14. A store arrangement according to claim 12, comprising a check selection station which, through the customer pass, determines the identity of the client and the associated check parameter and which, starting from the check parameter, determines automatically whether a check should take place;

and which, in case a check is to take place, guides the client to a check cash desk.

15. A store arrangement according to claim 14, wherein the check selection station, depending on whether or not a check should take place, clears a passage to a check cash desk or the readout station.

16. A store arrangement according to claim 15, wherein the check cash desk is adapted for the conventional registration of articles but passes the result of that registration directly to the readout station.

17. A store arrangement according to claim 16, wherein the readout station is adapted to identify a customer pass.

18. A store arrangement according to claim 17, wherein the automatically operating device comprises a random generator.

19. A store arrangement according to claim 18, wherein the automatically operating device is a computer.

20. A store arrangement according to claim 19, wherein the computer is part of the readout station.

21. A method for checking articles selected by a store client and with respect to which certain article information on the articles is registered in a scanner by a client in a self-service store, wherein a customer pass is issued to each client who will make use of a self-registration system in selecting articles in the store and registering the article information regarding the articles, each customer pass including first client information identifying the client to whom the customer pass is issued, the registration system including information processing equipment for processing the first client information contained on said customer pass and the article information registered in the scanner, and one of the processing equipment and the customer pass including a check parameter, the parameter including second client information relating to whether the client'"'"'s use of the self-registration system is to be checked for accuracy after the client has registered the selected articles in the scanner;

the method comprising;

a) coupling the scanner to the processing equipment;

b) reading the article information regarding the articles as registered in the scanner by means of the processing equipment;

c) coupling the customer pass to the processing equipment;

f) carrying out a check if it is determined by means of the processing equipment that a check is to take place.

22. The method according to claim 21, wherein:

a) the check parameter is an integer; and

b) the step of determining whether a check should take place includes the steps of;

1) generating, by means of the processing equipment, a first random integer;

2) comparing, by means of the processing equipment, the random integer to a second integer; and
