ANTI-THEFT RFID SYSTEM AND METHOD THEREOF
First Claim
1. An anti-theft RFID system for monitoring the presence of a plurality of tagged items, each of the tagged items being attached to an RFID tag, the anti-theft RFID system comprising:
- an RFID reader, the RFID reader comprising an antenna and being configured to transmit an interrogating signal to the RFID tags and retrieve data from the RFID tags through the antenna;
a processor connected to the RFID reader and configured to process the data that the RFID reader retrieves from the RFID tags; and
a display connected to the processor and configured to display a result processed by the processor;
wherein;
the processor is configured to update a first counter value indicating the number of tagged items located within a predefined area and to update a second counter value indicating the number of tagged items being taken away from the predefined area; and
the display is configured to display the values of the first and the second counters and thereby to assist an operator to determine the occurrence of a security event by analyzing the values of the first and the second counters.

Abstract
An anti-theft RFID system for monitoring the presence of a plurality of tagged items is provided. Each of the tagged items is attached to an RFID tag. The anti-theft RFID system includes an RFID reader, the RFID reader including an antenna and being configured to transmit an interrogating signal to the RFID tags and retrieve data from the RFID tags through the antenna; a processor connected to the RFID reader and configured to process the data that the RFID reader retrieves from the RFID tags; and a display connected to the processor and configured to display a result processed by the processor. The processor is configured to update a first counter value indicating the number of tagged items located within a predefined area and to update a second counter value indicating the number of tagged items being taken away from the predefined area. The display is configured to display the values of the first and the second counters and thereby to assist an operator to determine the occurrence of a security event by analyzing the values of the first and the second counters. A method implemented by the system is also provided.

10. A method for detecting a security event for a plurality of tagged items, each of the tagged items being attached to an RFID tag, the method comprising:
-
transmitting an interrogating signal to the RFID tags and retrieving data from the RFID tags; processing the data retrieved from the RFID tags; and displaying a result of the processing;
wherein;the step of processing the data retrieved from the RFID tags comprises updating a first counter value indicating the number of tagged items located within a predefined area, updating a second counter value indicating the number of tagged items being taken away from the predefined area, and determining the occurrence of a security event by comparing the value of the first counter with an expected value and comparing the value of the second counter with zero. - View Dependent Claims (11, 12, 13)
