HiLetgo 125Khz EM4100 USB RFID ID Card Reader Swipe Card Reader Plug and Play with Cable First 10 Digit (Only Read 125kHz ID Card, Cannot Read IC Card. See Product Pictures)

The limitation of the device is that it only reads EM4100 or TK4100 125 kHz RFID chips and nothing else. The device works as intended. It doesn’t need any drivers as it is recognized as a keyboard by any Windows, Linux or Android system, basically any computer system that can recognize the USB keyboard. The limitation of the device is that it only reads EM4100 or TK4100 125 kHz RFID chips and nothing else. When it does read the chip, it takes 10 digits from the chip and sends it as the text string + enter as if you would input it from the keyboard. For example, 1234567890 followed by the enter key. Many people do not have a full understanding that 125 kHz cards have multiple formats such as EM4100, HIDH10301 IDTECK Motorolla Indala26, Kantech IoProxXSF, AWID, FECAVA FDXA, ISO FDX-B, Farpointe Pyramid, Viking, Joblotron, Paradox, Stanely, Keri, Gallagher and others. Those are all different cards. So if you bought it randomly just looking at 125 kHz frequency, it is very likely that you may have HIDH10301 or any other 125 kHz RFID chip that is incompatible with this reader.
