The ER300D is a 13.56MHz contactless RFID reader module that functions as a USB HID keyboard device, requiring no drivers or programming for integration with Windows, Mac OS, Linux, Android, and iOS systems. It reads MIFARE Classic S20, S50, and S70 card/tag UIDs and outputs a 10-digit decimal serial number directly at the cursor position.

Features

  • Plug-and-Play USB HID Keyboard Device – No drivers or software installation required for Windows, Mac, Linux, Android, or iOS.
  • Reads MIFARE Classic S20, S50, and S70 RFID Cards/Tags – Outputs a 10-digit decimal serial number derived from the card’s UID.
  • Integrated Detection for Cloned UID Cards – Audible buzzer alerts (two beeps) when a cloned card is detected, with no data output.
  • Low-Power USB Bus Operation – Powered directly from a 5V DC USB port, compatible with mobile phone power sources.
  • Compact Desktop Form Factor – Features dual LED indicators and a built-in transceiver antenna with a typical read range up to 10 cm.

Description

The ER300D RFID reader operates at the 13.56 MHz frequency, utilizing inductive coupling to power and communicate with compatible passive RFID transponders. It emulates a standard USB Human Interface Device (HID) keyboard, allowing it to seamlessly interface with any system that supports USB keyboard input, eliminating the need for custom drivers or SDKs. Upon detecting a card, the reader converts the card’s hexadecimal Unique Identifier (UID) into a 10-digit decimal number and transmits it as keystrokes to the active application.

Engineered for reliability in office and light industrial environments, the module includes a built-in transceiver antenna, dual status LEDs, and an audible buzzer for user feedback. Its firmware includes validation logic to identify potential UID-cloned cards, triggering an alert without data transmission to enhance basic security. The compact, standalone housing is designed for desktop use with a typical read range of up to 10 cm.

Key Features

  • True Plug-and-Play USB HID Interface – Recognized instantly as a keyboard by all major operating systems, enabling zero-configuration deployment.
  • Wide Card Compatibility – Supports reading UID from MIFARE Classic 1K (S50), 4K (S70), and Ultralight (S20) RFID tags and cards.
  • Cloned Card Detection Logic – Integrated firmware feature provides a basic security layer by detecting and alerting to potential UID cloning attempts.
  • Low-Power, Bus-Powered Design – Draws minimal current from the host's USB port (5V DC), making it suitable for use with laptops, tablets, and mobile power banks.
  • Durable Construction for Office Environments – Housing designed for desktop use with operational stability across a temperature range of -10°C to 50°C.
  • User Feedback System – Equipped with a dual-color LED indicator and buzzer to signal power status, read success, and security alerts.
  • Optimized Read Performance – Fast reading time of less than 100 ms ensures quick and responsive card presentation workflows.

Applications

  • Employee Identification & Secure Physical Access Logging – Logging card swipes directly into spreadsheets or database forms for attendance.
  • Library Asset Management & Meeting Room Check-In – Rapidly cataloging items or registering attendees by scanning tags into existing software.
  • Secure Print Release Stations & POS Member Lookup – Authenticating users at shared printers or retrieving member accounts at points of sale.
  • Visitor Management & Time-Attendance Systems – Streamlining guest registration and staff clock-in/out processes with zero software integration.
  • Educational & Prototyping Environments – Providing a simple, programmable-free method for students and makers to capture RFID UIDs for projects.

Frequently Asked Questions

What type of RFID cards and tags is the ER300D reader compatible with?

The ER300D reader is designed to read the Unique Identifier (UID) from passive RFID cards and tags operating at 13.56 MHz, specifically those using the MIFARE Classic protocol. This includes MIFARE Classic 1K (S50), 4K (S70), and MIFARE Ultralight (S20) chips. It reads only the UID and does not access or manipulate data blocks on the card.

How does the ER300D interface with a computer or mobile device, and is any software required?

The ER300D interfaces via a standard USB port and emulates a USB HID (Human Interface Device) keyboard. This means it is recognized by the operating system as a standard input device, requiring no custom drivers, SDKs, or software installation. It is compatible with Windows, macOS, Linux, Android, and iOS systems that support USB HID profiles.

What does the reader output when it scans a card, and how is the data formatted?

When a valid card is detected, the reader converts the card's hexadecimal UID into a 10-digit decimal number. This number is then transmitted as a series of keyboard keystrokes, appearing at the current cursor position in any active text field, document, or spreadsheet. For example, a CubePilot UID of '04A1B2C3D4' would be output as a corresponding decimal string.

The description mentions cloned card detection. How does this feature work?

The reader's firmware includes logic to identify potential UID-cloned cards based on specific signal characteristics. When such a card is presented, the internal buzzer will sound two beeps as an alert. Crucially, the reader will not output any serial number data in this case, providing a basic layer of security against simple clone attacks. It is important to note this is a basic detection method and not a cryptographically secure authentication.

What is the typical operating range and power requirement for this RFID reader?

The ER300D has a typical read range of up to 10 cm (approximately 4 inches), depending on the card size and orientation. It is powered directly from the USB bus, requiring 5V DC, and draws very low current, making it compatible with standard USB ports on computers, laptops, USB hubs, and even some mobile power banks or phone chargers that provide sufficient power.
