Abstract

A price verification method for retail stores using shelf pricing, and apparatus therefor, in which the shelf labels are provided with an extended bar code having the item number and price of the item. A remote unit scans the item number and price, and uses the item number to look up the item in a database which is identical to the store checkout scanner database, and compares the shelf price to the database price. If they are not the same, a new shelf label may be printed immediately. Also, the UPC or other barcode on the product itself is scanned and compared to the shelf price label.

Claims

1. A method of shelf price and product placement verification for a store of the type utilizing checkout scanners and shelf pricing, comprising the steps of:

a) placing shelf price labels for each of a plurality of items in the store, each label having at least an item identification printed in barcoded form, and a price presented in both barcoded and human-readable form, and each item having at least an item identification printed in barcoded form;

b) scanning the shelf label, reading at least the item identification and shelf price;

c) looking up an item record from a store checkout scanner price database using the item identification, the item record containing at least the price for the item which would be used by the store checkout scanner;

d) comparing the shelf price from the scanned label to the price from the store checkout scanner price database;

e) if the shelf price from the scanned label is not equal to the price from the store checkout scanner price database, presenting an indication of a price error to an operator;

f) scanning the item, reading at least the item identification;

g) comparing the item identification from the scanned label and the item identification from the scanned item; and

h) if the item identification from the scanned label and the item identification from the scanned item do not match, presenting an indication of an item mismatch to the operator.

2. The method of claim 1, further comprising, in step "e" thereof, printing a new shelf price label containing at least the item identification printed in barcoded form, and the correct price from the store price database presented in both barcoded and human-readable form.

3. The method of claim 1 in which the item identification in barcoded form printed on the shelf price label is the UPC barcode for the item.

4. The method of claim 3 in which the UPC barcode for the item is extended to also barcode the price of the item.

5. The method of claim 1 in which the item identification in barcoded form printed on the item is the UPC barcode for the item.

6. The method of claim 1, in which steps b) and f) are executed one after the other in either order, and further comprising the step, after completion of both scans, such that the scan of step b) is defined as the scan in which the price code is detected in the scanned data.

7. A portable shelf price and product placement verification unit, for use in a system wherein a plurality of items in a store are identified with shelf price labels, each label having at least an item identification printed in barcoded form, and a price presented in both barcoded and human-readable form, and each item having at least an item identification printed in barcoded form, comprising:

a) scanner means for reading at least the item identification and shelf price from the barcode on the shelf price label and the barcode on the item;

b) memory means for storing at least the scanned item identification and the scanned shelf price from the barcode on the shelf price label;

c) database means for storing a plurality of item records, each record representing an item and containing at least an item identification and store checkout scanner price;

d) indicator means for communicating with the operator of the verification unit,

e) processor means for controlling the scanner means, memory means, indicator means and database means, such that;

i) when the scanner means has scanned a shelf price label, the processor means loads the item identification from the shelf price label into the memory means, looks up the item identification in the memory means in the database means, retrieves the associated item record for the item identified by the item identification, and compares the scanned shelf price and the price from the item record, and, if the shelf price and item record prices are not equal, provides a price error indication to the operator of the verification unit using the indicator means; and

ii) when the scanner means has scanned both the shelf price label and an item identification from an item, the processor means loads the item identification from the item into the memory means, compares it to the item identification from the shelf price label, and, if the item identification from the shelf price label and the item identification from the item do not match, provides an item mismatch indication to the operator of the verification unit using the indicator means.

8. The verification unit of claim 7, further comprising a printer, capable of printing the barcode and human-readable information on a shelf price label, operatively connected to the processor means such that when the shelf price and item record prices are not equal the processor means commands the printer to print a new shelf price label having at least the item identification printed in barcoded form, and the item record price presented in both barcoded and human-readable form.

9. The verification unit of claim 7 in which the item identification in barcoded form printed on the shelf price label is the UPC barcode for the item.

10. The verification unit of claim 9 in which the UPC barcode for the item is extended to also include a barcode for the price of the item.

11. The verification unit of claim 10 in which the store has a store computer controlling a plurality of checkout registers for scanning purchases by consumers, the database means is the database associated with the store computer which controls the checkout registers, and the portable verification unit further comprises a remote data link between the portable verification unit and the store computer.

12. The verification unit of claim 11 in which the remote data link uses radio frequency (RF) communications.

13. The verification unit of claim 11 in which the remote data link uses infrared (IR) communications.

14. The verification unit of claim 7 in which the item identification in barcoded form printed on the item is the UPC barcode for the item.

15. The verification unit of claim 7 in which the price error indication is an audible alarm.

16. The verification unit of claim 7 in which the price error indication is a visual display.

17. The verification unit of claim 7 in which the item mismatch indication is an audible alarm.

18. The verification unit of claim 7 in which the item mismatch indication is a visual display.

19. The verification unit of claim 7 in which the database means is a mass storage device located in the portable verification unit.

20. The verification unit of claim 19 in which the mass storage device is a magnetic disk drive.

21. The verification unit of claim 19 in which the mass storage device is an optical disk drive.

22. The verification unit of claim 19 in which the mass storage device is solid state Random Access Memory (RAM).

23. The verification unit of claim 19 in which the portable verification unit further comprises input/output means for communicating with a store computer, whereby the database of item records can be downloaded from the store computer to the database means of the portable verification unit.

24. The verification unit of claim 7 in which the indicator means also indicates when the shelf price and item record price are equal.

25. The verification unit of claim 7 in which the indicator means also indicates when the item identification from the shelf price label and the item identification from the item match.
