The USB Proximity Sensor Smart RFID ID Card Reader Module 125KHz – JT308 is a high-performance contactless RFID card reader designed for secure identification, attendance systems, access control, authentication, and RFID-based data acquisition. Operating at the standard 125KHz low-frequency RFID band, the JT308 provides fast and reliable reading of EM4100, EM4200, TK4100, and other compatible 125KHz RFID cards and key fobs. Featuring a USB interface with plug-and-play operation, the reader functions as a USB HID keyboard device, making it ideal for computers, attendance systems, security applications, POS terminals, membership management, educational institutions, and industrial access control systems.
Powered directly through the USB interface, the JT308 RFID Reader requires no external power supply or additional drivers under most operating systems. Simply connecting the reader to a computer enables automatic card number transmission as keyboard input, allowing seamless integration with existing software applications. Its advanced RFID decoding circuitry ensures fast response, high reading accuracy, and reliable operation while minimizing read errors and interference during continuous use.
The USB Proximity Sensor Smart RFID Reader features a compact ABS enclosure, integrated antenna, LED status indicator, and audible buzzer for instant user feedback during successful card detection. With a typical reading distance of up to 8cm depending on the RFID card and operating environment, the reader offers convenient contactless operation for offices, schools, hospitals, factories, hotels, libraries, parking systems, and security installations. Its durable construction and maintenance-free operation make it suitable for long-term professional use.
Designed for students, hobbyists, software developers, system integrators, engineers, security professionals, and automation developers, the USB Proximity Sensor Smart RFID ID Card Reader Module 125KHz – JT308 is compatible with Windows, Linux, macOS, and other operating systems supporting USB HID devices. It is widely used in employee attendance systems, visitor management, membership systems, authentication software, access control applications, educational laboratories, and RFID learning projects requiring reliable 125KHz RFID card reading.
