The invention is an ultra-miniature transceiver technology that allows positioning, data relaying and identification in a very tiny form factor (e.g., “pinhead” size). The transceiver is based on a system-on-a-chip (SOC) design of a radio frequency (RF) transceiver that is combined with a micro-miniature battery and an antenna (or in some cases two antennas). The invention enables communication to the transceiver through a generic RF pulse at a given frequency. The RF pulse activates the tag - which in turn modifies the carrier frequency transmitted in the activation pulse - modulates a data code and transmits the signal back to the interrogator. The activation-response cycle can be repeated multiple times to construct a communications message, data stream or the like. The size of the tag can be very small, approximately 1 x .5 mm and weighs approximately 10 milligrams and can easily be modified to work at virtually any frequency of interest.
