Abstract

Systems and techniques for retail product transaction processing and security tag deactivation analysis. Upon detection of a security tag deactivation associated with entry of product information into a retail transaction, product information for the product is analyzed to determine whether the security tag deactivation is legitimate or possibly illegitimate. Upon identification of a deactivation as possibly illegitimate, an alert is issued to a retailer employee to investigate the transaction. The product information may be updated according to an entry made by the retailer employee identifying the deactivation as legitimate or illegitimate. Product information for a product may include a deactivation count for a product, with a deactivation being identified as possibly illegitimate if the deactivation count does not meet a predefined threshold, the deactivation count being incremented if a deactivation identified as unexpected is determined to be legitimate.

Claims

1. A retail checkout terminal, comprising:

a security tag deactivation device for deactivating a security tag affixed to a product presented for entry into a transaction;

a deactivation detector for detecting a deactivation of the security tag; and

a processor for receiving a deactivation detection indication from the deactivation detector that a security tag has been deactivated and evaluating the deactivation detection indication in light of information associated with the product to determine if deactivation of a security tag is to be expected for a transaction involving the product.

2. The checkout terminal of claim 1, wherein the processor is operative to access a repository for product information, the product information including an entry for each product that may be submitted for entry into a transaction, the processor being operative to examine each entry for information indicating whether a deactivation of a security tag is to be expected for a transaction involving the product.

3. The checkout terminal of claim 2, wherein one or more product entries may include a deactivation count indicating a number of times a deactivation has been detected in association with a transaction entry associated with the product, wherein the processor is operative to evaluate a deactivation associated with a product as expected if the deactivation count for the product meets a predefined threshold and wherein the processor is operative to evaluate the deactivation associated with the product as unexpected if the deactivation count for the product does not meet the predefined threshold.

4. The checkout terminal of claim 3, wherein the processor is operative to make a decision as to whether an unexpected deactivation is legitimate or may be illegitimate.

5. The checkout terminal of claim 4, wherein the processor is operative to issue an alert to a retailer employee upon determining that a deactivation may be illegitimate.

6. The checkout terminal of claim 4, wherein the processor is operative to update the deactivation count for a product if a deactivation is determined to be unexpected but no determination is made that the deactivation may be illegitimate.

7. The checkout terminal of claim 3, wherein one or more product entries may include explicit information indicating whether or not the product bears a security tag.

8. The checkout terminal of claim 7, wherein the processor is operative to receive an entry from a retailer employee indicating whether or not a product bears a security tag and to update the product entry for the product based on the entry from the retailer employee.

9. The checkout terminal of claim 7, wherein the processor is operative to perform automated learning when a deactivation is detected in connection with a product for which no previous deactivation has been detected, in order to establish an expectation as to whether a deactivation is or is not to be expected in connection with transactions involving the product.

10. The checkout terminal of claim 9, wherein the automated learning takes into account information relating to a product and associated with a greater or lesser likelihood that such a product will bear a security tag.

11. A method of transaction processing and security tag deactivation analysis, comprising the steps of:

receiving an indication of a security tag deactivation in association with presentation of information for a product for entry into a transaction; and

analyzing product information for the product to determine whether or not the security tag deactivation is unexpected.

12. The method of claim 11, wherein the step of analyzing product information includes comparing a deactivation count for detected deactivations associated with the product to determine whether the deactivation count meets a predefined threshold and identifying the deactivation as unexpected if the deactivation count does not meet the threshold.

13. The method of claim 12, wherein the step of analyzing product information includes determining whether an unexpected deactivation is legitimate or illegitimate.

14. The method of claim 13, wherein the step of analyzing product information is followed by a step of alerting a retailer employee to investigate the transaction if the deactivation is identified as illegitimate.

15. The method of claim 14, wherein the step of alerting the retailer employee includes receiving an entry from a retailer employee indicating whether the deactivation is legitimate or illegitimate and updating the deactivation count for the product if the entry indicates that the deactivation is legitimate.

16. The method of claim 14, wherein the step of alerting the retailer employee includes receiving an entry from the retailer employee indicating whether or not the product bears a security tag and updating the product information in accordance with the entry.

17. The method of claim 11, wherein the step of receiving the deactivation indication is preceded by a step of storing product information for a plurality of products for which product information may be entered into a transaction, the product information for one or more products including information that may be analyzed to determine whether a security tag deactivation associated with the product is expected or unexpected.

18. The method of claim 17, wherein the information that may be analyzed includes price information for the product.

19. The method of claim 18, wherein the information that may be analyzed includes size information for the product.

20. The method of claim 17, wherein the product information includes an explicit indication for one or more products that the product bears or does not bear a security tag.
