MIFARE Classic Tool - NFC card reader

This is a low-level tool for reading, writing, and analyzing MIFARE® Classic RFID tags. It is tailored for users with basic familiarity with MIFARE® Classic technology and offers specific features to interact solely with MIFARE® Classic RFID-Tags.

Getting Started:

Obtain Keys: To read or write an RFID tag, you first need the keys specific to that tag1. Tools like Proxmark3, normal RFID readers, and special software (mfcuk, mfoc) can retrieve keys.

Key Files: The application comes with standard key files called std.keys and extended-std.keys, which contain well-known keys13. Changes to these files will be lost, so create your own key file for your keys.

Create Key File: Create a simple text file (one key per line) on your computer and import it using MCT's import/export tool, or create a new key file via "Edit or Add Key File" from the main menu17. Key files are simple text files containing one MIFARE Classic key per line (hexadecimal, 6 bytes, 12 characters)17. Lines starting with # and empty lines are ignored.

Read Tag: Use the "Read Tag" option from the main menu after setting up your key file.
