Abstract

A transmission mode of an interrogation from an RFID reader is the basis for determining a responsive communication. Transmission modes matching a pre-defined pattern are the basis for returning expected information, such as an identification code. When the received interrogations do not match a transmission mode, information not helpful in identification is returned, such as, for example, a null code, an incorrect code, or an error code. An RFID tag includes a circuit for analyzing frequencies of the received interrogation, the analysis revealing the transmission mode, which may include frequency value or range, duration of transmission, and number of frequencies received during the interrogation.
