RFID electronic anti-counterfeiting tags are very common in our lives. RFID is similar to barcode scanning, but RFID uses a special RFID reader and RFID electronic tag that can be attached to a target, and uses frequency signals to transfer information from the RFID electronic tag To RFID reader. If the RFID electronic label fails, it will not be able to scan and apply, then under what circumstances the RFID electronic anti-counterfeiting label fails
There are three cases of RFID tag failure:
The first case: the label is damaged
RFID tags have chips. If the chips are pressed by external force or high static electricity, they may fail. Antenna, if the RFID signal is damaged by the antenna, it will cause failure. Therefore, RFID electronic tags must not be damaged or torn by compression. Generally demanding RFID electronic tags will be packed in plastic cards to avoid damage by external forces.
The second case: the label is not damaged
RFID tags cannot penetrate metal, so metal can be shielded. It is difficult to penetrate water, water can absorb waves, and 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 third case: the reading distance is too far
In the actual application of high-frequency RFID electronic tags, we need to focus on the fitting position of the 13.56MHz RFID electronic tags. Due to the large size of the tags and the limited space allowed, the RFID electronic tags need to be directly attached to the metal On the surface or close to metal devices, such as 13.56MHz RFID smart tags for mobile phones, because of space problems, they are often directly integrated on the aluminum alloy stamping shell of the battery. In this way, during the identification process, RFID electronic tags It is susceptible to the eddy current interference of the aluminum alloy metal stamping shell of the battery, so that the actual effective reading distance of the RFID tag is greatly shortened or simply does not respond, and the reading fails completely. Practice has proved that such interference problems occur frequently, and we need to take certain measures to prevent them.
Under what circumstances will RFID electronic tags fail? Just share it here. We must avoid the above situations when using RFID electronic tags. Only in this way can we avoid the failure of RFID electronic tags as much as possible.
