Abstract

A RFID tag includes logic to compare information in a received signal with conditional response criteria, and to respond to the received signal with an RFID only if the information satisfies the conditional response criteria.

Claims

1. A device comprising:

an RFID tag, the RFID tag comprising an RF transceiver configured to receive signals from an RFID reader device;

logic to operate the RF transceiver to respond to a received signal from the RFID reader device with a unique radio frequency id (RFID) in a signal directed to the RFID reader device;

logic to compare a location indication in the received signal from the RFID reader device with a location indication stored by the RFID tag, and to respond to the received signal from the RFID reader device with the RFID in a response signal directed specifically to the RFID reader device only if the location indication stored by the RFID tag is co-extensive with the location indication in the received signal from the RFID reader device; and

logic to compare an operational state specified in the received signal with an operational state of the RFID tag, and to respond to the received signal from the RFID reader device with the RFID only if the operational state of the RFID tag matches the operational state specified in the received signal.

2. The device of claim 1, further comprising:

logic to compare an RFID type in the received signal with a type of the RFID tag, and to respond to the received signal with the RFID only if the RFID type in the received signal from the RFID reader device from the and the type of the RFID tag match.

3. The device of claim 1, further comprising:

logic to compare data in the received signal with data received and stored by the RFID tag prior to receipt of the received signal, and to respond with the RFID only if the data received and stored by the RFID tag is present in an RFID memory.

4. The device of claim 3, further comprising:

to respond with the RFID only if the data received and stored by the RFID tag is present in the RFID memory and the data received and stored by the RFID tag matches a criteria specified by the received signal.

5. The device of claim 1, further comprising:

logic to apply a password in the received signal from the RFID reader device with a password stored in the RFID memory and to respond to the received signal from the RFID reader device only if the password in the received signal from the RFID reader device matches the password stored in the RFID memory.
