Abstract: An electronic article surveillance and identification tag (1) and system is provided. The tag couples energy from a radiated energy source, which comprises first and second radiated signals. A mixing member (4) in the tag mixes the first and second signals to produce a sideband of the first signal, which is re-radiated by the tag. The mixing member is activated by a controller (6) that switches the mixing member into and out of the circuit according to a code stored within the controller that is associated with an article to be identified. As the mixing member is activated and deactivated, the sideband is radiated in a sequential manner according to the stored code. A receiver detects the sideband, and a decoder recovers the stored code according to the sequence of received sideband emissions from the tag.
