Setup
- Connect the Device: Connect the RFID Reader to your computer using the provided USB cable. The device should be recognized automatically.
- Install Drivers and Software:
For full functionality, especially for writing operations, install the necessary drivers and software from the included CD/USB drive or download them from the manufacturer's website. The software for writing Mifare Classic 1K/4K card sector data is only supported on Windows.
- Select Operating Mode: The reader has three integrated working modes, which can be switched using the provided configuration card. Refer to the "Data Format List and Reader Function Settings" section for details on output formats and reader function settings.
Operating Instructions
1. Reading Mifare Card UID (Keyboard Input Mode)
In this mode, the reader acts as a keyboard input device, outputting the UID of 14443A Mifare cards directly into any text editor or application. This includes Mifare Classic, UltraLight, Mifare Plus, Mifare Desfire, and Mifare N-TAG/card emulation.
- Ensure the reader is in the correct UID Reader mode (configured via the config card).
- Open a text editor (e.g., Notepad, Word) or any application where you want the UID to appear.
- Place a compatible 13.56MHz Mifare card on the reader. The UID will be automatically typed into the active input field.

2. Writing Mifare Card Data (Windows Software Only)
The writer mode utilizes USB 2.0 communication and dedicated Windows software to program sector data on Mifare Classic 1K/4K cards. This mode is essential for advanced operations like cloning or modifying card data.
- Ensure the reader is connected to a Windows PC and the writing software is installed.
- Open the Mifare writing software (e.g., "FissaiD MF Writer" or similar).
- Place the Mifare Classic 1K/4K card you wish to write to on the reader.
- Follow the software interface to read existing data, modify sectors, and then write the new data to the card.
