An RFID (Radio-Frequency Identification) reader is a device used to read and decode information embedded in an RFID card or tag. It communicates with the RFID card or tag through radio frequency signals and reads data from it.
The functions of RFID Card Reader are as follows:
Identification and Detection: RFID readers are able to identify and detect nearby RFID tags or cards. When an RFID card or tag comes into range of a reader, the reader sends out a radio frequency signal and receives the signal sent back by the card/tag.
Read data: The card reader reads the embedded information from the RFID card or tag, such as identification number, product serial number, inventory information, logistics tracking information, etc. This information can be stored in the chip of the RFID card, and the data can be read by a card reader through wireless communication technology.
Integrated into systems: Readers are often used integrated with computer systems, access control systems, or other automation systems. The reader can transmit the read data to the system for recording, processing, control, or other operations.
Improve efficiency and convenience: The use of RFID Card Reader can improve the efficiency and accuracy of data reading. They can quickly read information from large numbers of cards or tags without the need for contact reading, providing convenience for automated processes in a variety of scenarios.
Security: RFID technology can also be used for access control and authentication. For example, in an access control system, an RFID card reader can read an employee's work card and control access based on their permissions.
Generally speaking, RFID Card Reader reads the information in embedded RFID cards or tags through wireless communication technology, providing many application fields, including logistics, inventory management, identification, access control systems, etc., improving the efficiency and efficiency of information reading. Convenience.
