A RADIO FREQUENCY IDENTIFICATION (RFID) SECURITY DEVICE

摘要

A Radio Frequency Identification (RFID) tag device is configured as an electronic key. The electronic key disables the RFID Input/Output (I/O) by shorting or breaking the conductor between the RFID tag device and its resonant circuit or antenna whenever the electronic key is not inserted into a lock. This is a security measure which prevents unauthorized individuals from reading the electronic key code via a covert/concealed reading device. The circuit is completed by closing the key contacts with a matching shorting bar (normally open application), or spreading the shorted spring contacts with a nonconductive spacer (normally closed application) when the electronic key is inserted inside an electronic locking mechanism. Once the circuit is completed, the wireless transmission of data from the electronic key to the electronic locking mechanism is enabled.
