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 method of preparing information usable in theft detection using radio frequency identification (“

RFID”

) technology, comprising steps of;

reading, from an RFID tag affixed to each of one or more presented items, identifying information for that item; and

storing the identifying information for each item on a receipt reflecting the presented items.

2. The method according to claim 1, wherein the identifying information is stored on the receipt as an enumerated list if more than one item is presented.
