Abstract: An anti-theft RFID system for monitoring the presence of a plurality of tagged items includes an RFID reader including an antenna and being configured to transmit an interrogating signal to the RFID tags and retrieve data; a processor 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.

Abstract: A barcode and RFID reading apparatus includes: a micro-controller; at least a RFID antenna configured to detect a RFID tag in a first area proximate to the reading apparatus; a RFID reader connected to the at least one antenna and controlled by the micro-controller, the RFID reader being configured to receive a RFID tag data from the at least one antenna and send the RFID tag data to the micro-controller; and a barcode reader controlled by the micro-controller, the barcode reader being configured to detect a barcode in a second area proximate to the reading apparatus and send a barcode data from the barcode to the micro-controller; the micro-controller is configured to check whether the barcode reader or the RFID reader ends a data-reading process; if one reader ends the data-reading process, the micro-controller switches off the one and switches on the other.
