RFID card reader is a device that can read RFID electronic tag data and is widely used in various automated identification scenarios. RFID readers communicate with tags through wireless radio frequency technology to obtain data stored in the tags. Its main components include reader antenna, processor, power supply and interface, and control unit. The reader antenna is responsible for transmitting and receiving radio frequency signals, and the processor parses and processes the received data and transmits it to the corresponding application. The power supply and interface provide power and connect the reader with other devices, while the control unit controls the operation and configuration of the reader. RFID readers are widely used in many fields, including logistics management, inventory tracking, access control, asset management, etc. They can communicate with other devices such as computers, smartphones, access control systems, etc. to meet various application requirements. For example, in logistics management, RFID readers can be used to track goods; in access control, they are used to identify and control access rights.
