In which specific year did Mario W. Cardullo receive the patent for his active radio frequency identification system?

Answer

1973

Mario W. Cardullo achieved a significant historical milestone by securing a patent in the year 1973 for what was documented as an active radio frequency identification system. This system functioned as an active transponder, meaning it possessed its own integrated power source, which allowed it to broadcast a signal when prompted by an external reader. Although this initial invention proved that remote electronic reading of data was technically achievable and capable of surpassing limitations of non-electronic identification methods, the requirement for this battery power prevented it from becoming the immediate backbone of high-volume, low-cost supply chain management.
