Abstract
A RFID tag includes an RF transceiver; logic to operate the RF transceiver to respond to a received signal with a unique radio frequency id; logic to compare information in the received signal with conditional response criteria; and logic to determine if data has been received and written into a writable memory area by the RFID tag, and to respond to the received signal only if the data has been received and stored in the writable memory area and matches the conditional response criteria.
