What causes rfid inventory tags to fail?

rfid inventory tags are relatively common in our lives, just like RFID is similar to bar code scanning, but RFID uses a special RFID reader and RFID tag that can be attached to a target, and uses frequency signals to transfer information from RFID The electronic tag is transferred to the RFID reader. If the RFID electronic label fails, it will not be able to scan and apply, so under what circumstances does the RFID electronic security label 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.

There is also the problem that the label is not damaged but cannot be applied. RFID electronic tags cannot penetrate metal, so the metal can be shielded. It is difficult to penetrate water, and because water can absorb waves, the sensing distance is limited. When covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood, and plastic, and can communicate penetratingly. The barcode scanner must be able to read the barcode only when it is close and there is no object blocking.

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.
