Advanced MIFARE® Classic Reader & Writer for Secure RFID Analysis and Tag Management

Master your MIFARE® Classic workflow with a professional tool built for precise reading, writing, cloning, and analyzing RFID tags. Designed for users familiar with MIFARE® Classic technology, this utility focuses on raw hexadecimal control, reliable authentication, and sector-level editing. It maintains all core functions while delivering clearer guidance and improved usability for technical RFID tasks.

Perfect for security testing, NFC research, and field debugging, this tool includes in-app offline help, open-source transparency, and powerful data utilities such as diff comparison, access condition decoding, and value block management. It’s built strictly for MIFARE® Classic tags—ensuring stable, predictable performance for every supported device.

Before using advanced functions, please review all instructions carefully. For additional documentation, troubleshooting, and updates, visit the official project resources.

IMPORTANT NOTES

This is a low-level technical tool. It does not provide consumer-friendly “write a URL” shortcuts; all data must be entered as raw hexadecimal. The app cannot hack, brute-force, or crack MIFARE Classic keys due to protocol limitations—you must supply valid keys beforehand. Some devices cannot use this tool because their NFC controllers lack MIFARE Classic support.

Original MIFARE Classic tags have a read-only manufacturer block. Only certain special “magic” tags allow writing to this block, and some require special command sequences that are not supported. Always confirm tag compatibility before use.
