JT308 USB RFID Reader 125 kHz with HID Keyboard Function

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The JT308 USB RFID Card Reader is a compact RFID reader designed for reading 125 kHz RFID cards and tags. It connects directly to a computer through USB and is recognized as a standard USB HID keyboard. This means that no additional driver is normally required and the reader can be used with almost any application that accepts keyboard input.

When a compatible RFID card or tag is presented to the reader, the unique card ID is read and automatically transmitted to the computer as keyboard keystrokes. In most cases the transmission ends with the Enter key, making the reader easy to use with forms, databases and other software without custom integration.

The built in antenna operates at 125 kHz and provides a typical reading distance of approximately 3 to 8 cm depending on the card type and surrounding conditions. The reader supports EM Series, EM4001 and compatible RFID cards.

Because the device behaves like a standard USB keyboard, it is suitable for a wide range of applications including membership management, access control, attendance systems, inventory management, point of sale systems, schools, businesses and other identification applications.

The reader can also be used together with automation software such as AutoHotkey or custom applications. This makes it possible to launch software, open files, log in to proprietary systems or perform other automated actions when a specific RFID tag is detected.

The device is powered entirely from the USB interface and consumes less than 0.5 W, allowing simple installation without an external power supply.
