RFID hollow inductor radio frequency identification technology, also known as radio frequency identification, is a communication technology, commonly known as electronic tags. A specific target can be identified by radio signals and the relevant data can be read and written without the need to establish mechanical or optical contact between the identification system and the specific target. In the smart card sensor, an rfid induction coil is installed. Mainly used in security system, public security system, medical system, attendance system, bus system and so on.

The RFID hollow inductance coil of the smart card sensor comprises a base plate and a coil body, and the coil body is fixed on the top of the base plate; The four support rods are fixed symmetrically on the top of the bottom plate, and the four support rods are rectangular distribution; The roof is movable and installed at the top of the four support rods; The four connecting slots are symmetrically arranged at the bottom of the top plate, and the connecting slots are adapted to the corresponding support rods; The card slot is arranged on the support rod; The card block is installed on the top plate, and the card block fits the corresponding card slot.
