Description

Professional 125KHz USB RFID Proximity Desktop Card Reader

The 125KHz RFID USB Proximity Desktop Card Reader is a high-reliability, driverless contactless smart card reader engineered for fast data capture and effortless integration into your existing desktop and web software workflows. Operating in the 125 kHz Low Frequency (LF) band, this reader instantly interrogates the unique 10-digit factory serial number of standard EM4100, EM4001, and TK4100 proximity cards, key fobs, and access control tokens.

True Driverless USB HID Keyboard Wedge Architecture

Belonging to the standard USB Human Interface Device (HID) class, the reader requires zero software drivers or third-party background services:

  1. Plug & Play Connectivity: Plug the 1.5-meter USB cable into any free USB port on your Windows, Mac, or Linux computer.
  2. Instant Self-Test: The device emits a crisp confirmation beep ('drip' tone) and flashes its diagnostic LED, completing its hardware self-test in less than 500 milliseconds.
  3. Direct Cursor Input: Place your cursor into Microsoft Excel, Word, Notepad, Google Sheets, or any browser-based web application form. When an RFID proximity card is tapped within 5 to 8 cm of the reader pad, the reader automatically types the 10-digit card number and issues an automatic [Enter] keystroke, advancing your cursor directly to the next line.

Ideal Commercial & Institutional Applications

  • Employee Attendance & HR Logging: Rapidly enroll new employee ID badges or record punch-in timestamps directly into spreadsheets without expensive biometric terminals.
  • Gym & Fitness Center Membership: Tap member keyfobs at the reception counter for instant check-in verification.
  • Library & School Student Tracking: Capture student card IDs at circulation desks or computer laboratory entry gates.
  • Visitor Management Systems (VMS): Issue temporary visitor access badges and log visitor check-ins at corporate reception desks.
  • Point-of-Sale (POS) Cashless Systems: Retrieve customer loyalty card numbers at billing counters seamlessly.

"Value for money at ₹800. Perfect for student attendance logging. Works without any drivers even on older Windows 7 PCs in our computer lab."

Questions

Does this 125KHz USB card reader require any driver installation?
No. The reader uses standard USB HID Keyboard Wedge architecture. It is recognized natively by Windows 11, Windows 10, Linux, macOS, and Android OTG as a standard USB keyboard. No drivers, DLLs, or third-party software are needed.
Can this reader write or reprogram 125KHz cards?
No. This unit is a dedicated high-speed read-only scanner designed specifically for EM4100 and EM4001 read-only proximity cards. If you need to write or clone 125KHz T5577 chips or 13.56MHz MIFARE cards, please check our RFID Reader/Writer programmer models.
How does the card number appear on my computer screen?
When you tap a 125KHz card within 5 to 8 cm of the desktop reader, it simulates typing the 10-digit decimal card number directly wherever your mouse cursor is focused (such as an active cell in Excel or an input field on a web page), followed by an automatic [Enter] key.
What is the warranty and return policy on this card reader?
RFID Softwares provides a comprehensive 1-Year Replacement Warranty on this card reader against any manufacturing or component defects, backed by pan-India technical support.
What is the HSN Code and GST tax rate for this reader?
This USB card reader is billed under HSN Code 84719000 (Automatic Data Processing / RFID Card Readers) with standard 18% GST. A valid GST tax invoice is issued for all corporate and individual orders.
