Abstract
A security method for a self-service checkout system with radio frequency identification (RFID) capability. The security method includes the steps of obtaining cart identification information from an RFID label attached to a cart by a security computer at a security station, obtaining first item identification information from a self-service computer transaction record using the cart identification information, obtaining second item identification information from a group of RFID labels attached to a group of items in the cart by the security computer, and comparing the first item identification information in the transaction record to the second item identification information to determine whether the second item identification information equals the first item identification information.
