Frequently Asked Questions
Q: What types of RFID cards does this USB reader support?
A: This dual frequency USB RFID reader supports both 125kHz cards (such as EM4100 and EM4200 format proximity cards) and 13.56MHz smart cards (including ISO 14443A/B and Mifare standard cards). This broad compatibility makes it suitable for most common access control cards, key fobs, and RFID tags.
Q: Do I need to install any drivers or special software to use this RFID reader?
A: No — this USB RFID reader operates as a plug-and-play HID keyboard device. Simply connect it to a USB port on your Windows, macOS, or Linux computer and it is ready to use immediately. Open any text-input application (such as Notepad, Word, or Excel), position your cursor, and the reader will type the card's ID number directly when a card is detected.
Q: What is the reading range for this proximity RFID reader?
A: The reading range depends on the card type and thickness, but typically falls within 3–8 cm for standard proximity cards. For best results, hold the card flat and parallel to the surface of the reader.
Q: Is this USB RFID reader suitable for building access control or attendance systems?
A: Yes. This reader is well-suited for integration into office access control setups, employee time-and-attendance logging, membership check-in systems, and inventory management applications. Because it outputs card data as keystrokes, it works with virtually any database, spreadsheet, or custom software that accepts text input.
