What type of system did Mario W. Cardullo patent in 1973?

Answer

Active transponder system

Mario W. Cardullo was granted a patent in 1973 for what is described as an active radio frequency identification system, specifically an active transponder. The defining feature of this active system was that the tag itself contained a power source, typically a battery, enabling it to broadcast a signal upon interrogation by a reader. This invention successfully proved the technological feasibility of remote electronic identification. However, the reliance on an internal battery introduced significant constraints, particularly high unit costs and the necessity for periodic power replenishment or replacement, which hindered its widespread adoption in high-volume logistics environments where low per-item cost is paramount.
