Customer Questions & Answers
Which operating systems is the 125 KHz EM4100 USB RFID reader compatible with?
The 125 KHz EM4100 USB RFID reader does not require specific drivers and generally works as a HID keyboard, so it is compatible with standard operating systems such as Windows, macOS and most Linux distributions. However, functionality may vary on embedded systems or very old versions.
What exactly is included in the box, and what are its physical dimensions?
The box includes the USB RFID reader, a USB cable and a basic manual. The reader measures 110 mm x 80 mm x 26 mm, which is a compact format suited to the size of an RFID card.
What maintenance does the reader require, and what service life can be expected under normal conditions?
Maintenance is minimal: simply clean the outer surface periodically to prevent dust build-up and ensure the USB connection is correct. It has no moving parts, so its service life exceeds 100,000 read cycles under standard conditions.
How does this reader compare with higher-frequency models, such as 13.56 MHz units, in terms of security and speed?
125 kHz readers like this one offer similar read speed, but in terms of security, 13.56 MHz readers (for example, MIFARE) usually provide better support for encryption and advanced authentication. This model is suitable for basic access control applications where high encryption standards are not required.
Does the USB RFID Reader 125KHz EM4100 need driver installation?
No, this RFID reader works without needing to install drivers, making it ready to use as soon as it is connected via USB.
What type of cards is this RFID reader compatible with?
It is compatible with EM4100 RFID cards operating at 125 KHz.
What is the maximum reading distance of the reader?
The maximum reading distance is approximately 8 centimetres.
Can this RFID reader be used for Arduino projects?
Yes, it is compatible for integration into electronic projects and Arduino-based systems that require RFID card reading.
What is included in the product package?
It includes the RFID reader module with female A-type USB connector and a USB cable for connection.
