Description

The R20C USB RFID Reader operates on the 13.56MHz frequency, utilizing inductive coupling to read the unique identifiers (UIDs) from compatible passive RFID transponders. It functions as a Human Interface Device (HID), emulating a keyboard to output the card’s 10-digit decimal serial number directly at the cursor position of any text field, enabling seamless data capture.

Engineered for reliability in office and light industrial environments, the module features a built-in transceiver antenna, dual-status LEDs, and an audible buzzer. Its bus-powered design draws minimal current from the USB host, making it compatible with mobile devices and standard PCs. The reader includes logic to detect potential cloned UID cards, providing a security alert without outputting data.

Key Features

  • Plug-and-Play USB HID Device for Universal OS Compatibility
  • Integrated 13.56MHz RF Circuitry and Antenna for Stable Reading
  • Cloned Card Detection Algorithm Enhances System Security
  • Dual LED Status Indicators and Buzzer for Operational Feedback
  • Compact and Durable Housing Suitable for Desktop Integration
  • Low-Power Design Operates from Standard USB Bus Power
  • Wide Operating Temperature Range for Indoor Applications

Applications

  • Employee Identification and Secure Physical Access Control Systems
  • Time and Attendance Logging Integrated with Spreadsheet or Database Software
  • Library Asset Tracking and Member Management
  • Visitor Registration and Meeting Attendance Logging
  • Secure Print Release and Point-of-Sale Member Validation

Frequently Asked Questions

What type of RFID cards is this reader compatible with?

This reader is specifically designed for 13.56MHz Mifare Classic cards, including the S20, S50, and S70 variants. It reads the card's Unique Identifier (UID) and outputs it as a 10-digit decimal number. It does not read or write other card data blocks or support other RFID protocols like EM4100.

Does this RFID reader require any software or driver installation?

No, the module is configured as a USB Human Interface Device (HID), specifically a keyboard. It is recognized as a standard keyboard by Windows, macOS, Linux, Android, and iOS operating systems upon plugging in via USB. You can capture card data by simply placing the cursor in a text field.

What is the power requirement and how is the reader powered?

The reader is bus-powered and operates on 5V DC supplied directly from the USB port. It draws minimal current, making it compatible with standard computer USB ports, USB hubs, and even some mobile power banks or phone chargers that provide data connectivity.

What happens when a cloned or duplicate UID card is detected?

The reader has built-in logic to detect potential cloned UID cards. When such a card is presented, the internal buzzer will sound twice as an alert. Critically, the reader will not output any serial number data to the computer, preventing unauthorized or duplicate entries in your system.

What is the typical read range and what factors affect it?

The maximum nominal read range is up to 10 cm (approximately 4 inches) under ideal conditions. Actual range can be affected by card orientation, the presence of metallic objects or other RF interference near the reader's built-in antenna, and the specific type/thickness of the Mifare card being used.
