What causes rfid inventory tags to fail?
There are three cases of rfid inventory tags failure. The first is the label damage. This is because there is a chip in the RFID electronic tag, so once the chip is pressed by external forces or damaged by high static electricity, it may cause failure. Antenna, if the RFID signal is damaged by the antenna, it will also cause failure. Therefore, RFID electronic tags must not be damaged or torn by compression. Generally required RFID electronic tags will be packed in plastic cards to avoid damage by external forces.
The reading distance is too far. In the actual high-frequency rfid inventory tags application, due to the larger tag size and the actual allowable space is limited, due to space problems, it is often directly integrated on the battery aluminum alloy stamping shell During the identification process, the RFID electronic tag will be easily interfered by the eddy current of the aluminum alloy metal stamping shell of the battery, resulting in the actual effective reading distance of the RFID tag being greatly shortened or simply not responding, and the reading fails completely.
