In the world of automatic identification and data capture (AIDC), few technologies have bridged the gap between theoretical physics and industrial logistics as effectively as Radio Frequency Identification (RFID). Yet, for many practitioners, the core of the technology remains a black box: . Dobkin is a technical guide focusing on the
