Selection of RFID Door Reader

Access control systems can be divided into password identification, card identification and biometric identification according to the entry and exit identification methods. Password recognition is to identify access permissions by checking whether the entered password is correct. Password recognition security is relatively high, but the password is easy to forget, and you need to enter the password every time you enter the door. There will be situations where your hands are not free to enter the password. In this way Seems inconvenient. Biometric identification is to identify people through some biological characteristics. Biometric identification is highly secure and very convenient, but its high cost makes it difficult to promote. Card recognition is divided into contact and non-contact. Magnetic cards are contact cards that appeared earlier and are the most widely used. However, magnetic cards have low security, are easy to wear and require frequent magnetization. RFID cards are the representative of non-contact identification cards. , which is cheap, easy to use, highly secure and can be well managed using a database, making it extremely cost-effective. The identification method of the rfid access control system needs to be selected based on the importance of the area and whether data recording is required.
 

The RFID access control system can manage important areas and data records at the same time. Through close range identification and comparison, it can make corresponding actions such as opening the door or maintaining the original state. The RFID access control system consists of electronic tags and readers. The electronic tag has an integrated antenna and chip inside and can be made into various forms such as work badges, temporary identity badges, etc. There are many styles of readers and writers. The most common one is a wall-mounted all-in-one machine specially used for access control. It integrates short-range card reading and simple permission setting and unlocking functions for access control. The external integrated three input interfaces and one relay output interface facilitate linkage with other devices. Usually used for closed door control.
 

Open channel access control, such as libraries, shopping mall entrances, etc., are usually integrated products, with RFID door reader being the most common. Antenna modules are arranged around the door, and readers and writers, together with other functional modules, are integrated inside the door. The electronic tags are built-in electronic tags for goods or books. When illegal electronic tags (unchecked goods or books that have not been borrowed) pass through the RFID door reader, the anti-theft function in the access control system will work and trigger an alarm.
 

The access control system used for identification and open channels is a conference sign-in machine, which looks like a RFID door reader and is usually used for participant management of large conferences and concert ticket management. The identities of the participants will be entered into the system in advance, and a unique identity tag will be generated. At this time, the identity tag is used as an electronic tag, and the built-in chip stores the corresponding personnel information. When a participant wears an admission ticket and passes through the check-in machine, the antenna on the door senses the corresponding tag, communicates with the reader in the door and compares the background data. The person's information can be displayed and marked on the attached screen or background. . When there is a fake ID tag or a fake ticket, the system background will compare the ID without such electronic tag and an alarm will be issued. Conference sign-in machines are generally suitable for important conference occasions, which can ensure the identity of each person entering and improve the safety of the venue.
