Nowadays, the access control system is no longer a mysterious high-tech product, but an increasingly civilian life safety product. However, in the face of such small technical problems, small faults and small problems are often impossible for many people. How can we troubleshoot the problems of the common Metal RFID Card Reader? Let me briefly introduce the cause and solution of the failure of Metal RFID Card Reader without reading the card.

Metal RFID Card Reader can not read the card is caused by what reason, if the access control system just used when everything is normal, the use of the card reader can not read the card for a period of time, to eliminate the problem:

Step 1, check if the power supply is working properly;

In step 2, check if the card reader is damaged.

In step 3, check for strong magnetic interference around the reader.

If the above steps are excluded, the Metal RFID Card Reader still does not read the card and can be determined as the following cause of failure:

The use of Metal RFID Card Reader equipment for some time will generate some static electricity. The accumulation of static electricity during normal time will cause excessive power consumption, and the shorter the use time, the problem is that the reader is aging too fast.

Solve the problem:

Before installation, you should select a dedicated power supply with good quality and high power. If this happens, the electric lock will be powered separately from the card reader, and a power supply will be provided to the card reader separately.

Metal RFID Card Reader slows down the sensing distance and eliminates the problem:

Step 1: Whether the card reader is mounted on metal;

Step 2: Whether to swipe in and out, such as entering and exiting the card to see how much the two readers are spaced.

cause of issue:

The Metal RFID Card Reader is mounted on metal. Because the metal has a shielding function, part of the electric wave emitted by the reader is shielded by metal. If the card is inserted and removed, the same problem will occur when the two card readers are installed too close. The two cards simultaneously emit radio waves. The interference between the radio waves will cause the card to be slow, and if the card is too close, the card will not be read.

Solve the problem:

During installation, observe the card reader installation environment. For example, the metal RFID Card Reader is made of metal behind it. When installing the card reader, install a plastic plate behind the card reader. If you want to get in and out of the card, the two readers should be staggered by 30CM. If conditions are not allowed, install a shield on one of the Metal RFID Card Readers.
