Abstract

Techniques are disclosed for detecting shoplifting or theft, particularly in a retail environment, using radio-frequency identification (“RFID”). Preferred embodiments leverage RFID tags on merchandise and RFID data that is written at the point of sale on the merchandise-borne RFID tags themselves, on the customer'"'"'s receipt, or both. Some embodiments also leverage RFID tags on customer identification or “loyalty” cards. After writing RFID data on the merchandise-borne tags and/or receipt, a matching operation is performed at an RFID reader when the shopper and his merchandise exit the premises, in order to determine whether the shopper has paid for the items in his possession.

Claims

1. A computer program product for preparing information usable in theft detection using radio frequency identification (“

RFID”

) technology, the computer program product embodied on one or more computer-readable media and comprising;

computer-readable program code for reading, for a current transaction, a customer identifier from a customer loyalty card; and

computer-readable program code for storing, during the current transaction, the customer identifier in an item-identifying RFID tag affixed to each of at least one items being paid for by a shopper in the current transaction, such that the RFID tag affixed to each of at least one items possessed by the shopper can subsequently be searched to determine whether the at least one possessed items were paid for in the current transaction.

2. The computer program product according to claim 1, wherein the customer identifier is read with an RFID reader from a loyalty card RFID tag affixed to the customer loyalty card.

3. The computer program product according to claim 1, further comprising:

computer-readable program code for subsequently searching, for each of the at least one items possessed by the shopper, the item-identifying RFID tag affixed to the item to determine whether the customer identifier from the customer loyalty card was previously stored therein; and

for any of the subsequently-searched item-identifying RFID tags for which the customer identifier is determined not to be previously stored therein, computer-readable program code for concluding that the item to which the item-identifying RFID tag is affixed was not paid for in the current transaction.

4. A computer program product for detecting potential theft using radio frequency identification (“

RFID”

) technology, the computer program product embodied on one or more computer-readable media and comprising;

computer-readable program code for reading, from a customer loyalty card possessed by a shopper, a customer identifier;

computer-readable program code for searching, for each of at least one items possessed by the shopper, an item-identifying RFID tag affixed to the item to determine whether the customer identifier from the customer loyalty card was previously stored therein during a particular purchase transaction; and

computer-readable program code for concluding that one or more selected ones of the items possessed by the shopper were not paid for in the particular purchase transaction if the computer-readable program code for searching fails to locate the customer identifier in the RFID tag affixed to the selected ones.

5. The computer program product according to claim 4, wherein the customer identifier is read from a loyalty card RFID tag affixed to the customer loyalty card.

6. The computer program product according to claim 4, further comprising computer-readable program code for storing the customer identifier in the item-identifying RFID tag affixed to each of the items when the items are paid for during the particular purchase transaction, prior to operation of the computer-readable program code for searching.

7. The computer program product according to claim 4, further comprising computer-readable program code for remembering each item that was in the shopper'"'"'s possession when the shopper entered an establishment in which the particular purchase transaction was conducted, and wherein the computer-readable program code for searching and computer-readable program code for concluding omit the remembered items.
