Metal RFID Card Reader is an important part of the access control system. It is a series of tasks such as reading card information, man-machine interface interaction, and data verification upload. In recent years, as security and security issues have become more and more important, the access control system has shown a rapid development posture, which solves the problems of people's security and management at the entrance and exit.
With the increasing use of Metal RFID Card Reader, it is inevitable that some common faults will occur as electronic products. As a peripheral device, Metal RFID Card Reader is the most vulnerable and most common problem in access control systems. Friends who have been exposed to access control products are no strangers to the following situations: after a period of time, the card cannot be recognized and the card swipe speed is slow. After a long time, you need to stick the card close to the card reader to recognize the success, the card reading distance becomes very short; when the voltage is unstable, the card cannot be recognized, and some even directly scrap; in the case of excessive temperature, excessive or collision When the body is prone to cracks.
If the Metal RFID Card Reader has just been installed, everything will be normal. After a period of time, the card reader cannot read the card, or the card cannot be read normally. Exclude some problems caused by the intention:
Step 1, check if the power supply is working properly;
Step 2, check if the card reader, receiver, and server are damaged.
In the third step, check whether the connection of each component is normal. The fourth step is whether there is strong magnetic interference around the reader.
Sometimes, the Metal RFID Card Reader reads slower and the sensing distance gets closer. This is inconvenient to use. If this problem occurs, you can do it in two steps:
In the first step, check whether the Metal RFID Card Reader is mounted on metal. If the card reader is mounted on metal, the metal wave is shielded. The part of the wave emitted by the reader is shielded by metal. This causes the transmitted transmission and reception distance to become close.
In the second step, check whether the card is in and out. If it is in and out, check the distance between the two readers. The distance is too close. The electromagnetic waves between the two readers affect each other. The two cards simultaneously emit radio waves. Mutual interference can cause slow reading, and too close readers will not read the card.
In addition to the failure of the Metal RFID Card Reader, if you encounter an unsolvable problem, you can look for professional maintenance personnel to deal with it.
