The UHF reader(inductive IC card) is an important part of the access control system and the key device for the signal input of the access control system. If the access control system is compared to a person, the card reader is like a person's eyes.
It is related to the stability of the entire access control system. If an access control system controller and Electric Bolt lock are good, if there is a problem with the quality of the card reader, it will also cause the door to be unable to open, which will affect the acceptance and use of the project.
The card reader can be divided into IC card readers and ID card readers from the card reader type. IC card reader is a non-contact IC card reading and writing device. It is connected to the PC through the USB interface. Access control power supply or keyboard port to take power, it supports access to all functions of the RF card. This series of equipment is used in access control, attendance, conference check-in, highway, tourism, parking lot, bus toll, shopping mall consumption, membership system and card issuance system of various application systems.
The card reader emits electromagnetic waves at a fixed frequency. The frequency is generally 13.56MHZ. When the induction card enters the electromagnetic wave radiation range of the card reader, it will trigger the coil on the induction card, generate current and trigger the antenna on the induction card to read the card. The card reader transmits a signal with card information, and the card reader converts the level signal into a digital serial number and transmits it to the local controller. The local controller uploads the information to the upper controller and finally uploads it to the access control server. The server compares the card number with the information in the database to obtain all the card information.
