Default Title

USB RFID Reader — 125kHz EM4100 / TK4100 & 13.56MHz S50 / S70, Plug-and-Play

This dual-frequency USB RFID reader supports both 125kHz (EM4100, TK4100, HID Prox) and 13.56MHz (Mifare S50, S70, ISO 14443A) RFID card standards in a single compact device. It connects via USB and appears as a standard HID keyboard device — no drivers required on Windows, Linux, or macOS. When a card is presented, the reader outputs the card UID as keystrokes directly into any text field, making it instantly compatible with any software that accepts keyboard input.
