The LUCKING DOOR R20D USB RFID reader is fully plug-and-play with Windows 2000, XP, 7, 8, and 10. No driver installation is required. Most Windows 11 systems also recognize it automatically via the same HID keyboard emulation protocol, though we recommend confirming with Windows 11 compatibility before purchase.\u003c\/p\u003e\n\u003ch4\u003eQ: What types of RFID cards work with this reader?\u003c\/h4\u003e\n\u003cp\u003eA: This reader supports all standard 125KHz passive RFID cards and key fobs using the EM4100 or TK4100 chip format. It will NOT read 13.56MHz cards (such as Mifare or HID iClass). Make sure your existing cards are 125KHz EM4100\/TK4100 before ordering.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the reader output the card number to my computer?\u003c\/h4\u003e\n\u003cp\u003eA: The reader emulates a USB keyboard (HID device). When a card is scanned, it automatically types the card's ID number — followed by an Enter keystroke — directly into whatever active text field or application is open on your screen. No special software is required.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this reader on a Mac or Linux system?\u003c\/h4\u003e\n\u003cp\u003eA: The reader is primarily designed and tested for Windows. However, because it uses standard USB HID (keyboard emulation), many Mac and Linux users report successful use without drivers. Compatibility on non-Windows systems is not officially guaranteed by the manufacturer.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this USB RFID reader compatible with Windows 10 and Windows 11?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
