Would you like a comparison with MCT Next, or help using a specific feature?

Before you begin, make sure you have:

Because MIFARE Classic Tool can clone cards or modify data in some scenarios, it is frequently used by security professionals for penetration testing

Not all Android phones are compatible with MIFARE Classic tags due to limitations in their NFC controller hardware. The application includes an "Editor Only" mode for such devices. You can check the official project page for a list of incompatible devices. mifare classic tool 2.3.1

: Users often use MCT to clone "Magic Cards" (Generation 1 Chinese Magic Cards), which allow the UID in Block 0 to be rewritten—something impossible on original MIFARE cards. Technical Limitations Hardware Dependence

MCT cannot execute complex cryptographic attacks like the "Darkside" or "Nested" attacks. It is a reader/writer tool. To break unknown keys, you must first sniff or crack the keys using dedicated hardware like a Proxmark3 or Flipper Zero, then import those keys into MCT. Ethical and Legal Compliance

Ensure your Android device has a working NFC chip. Install MCT and grant the necessary permissions: NFC control and access to shared storage for saving files. For the cloning process, you will need two items: the source tag you wish to copy and an empty, writable tag. Would you like a comparison with MCT Next,

MIFARE Classic is an aging technology. Its security relies on the CRYPTO1 algorithm, which has been publicly compromised for years. Tools like MCT 2.3.1 highlight these vulnerabilities by demonstrating how easily data can be cloned or modified if the encryption keys are discovered. It is vital to use MCT responsibly:

: The interface is low-level, requiring users to input and understand raw hexadecimal data. Availability

Mifare Classic Tool,简称MCT,是由开发者IKARUS Projects推出的一款运行于Android操作系统的低层应用程序。正如其名,这款工具非常纯粹,它只专注于与MIFARE Classic类型的RFID标签进行交互(包括但不限于MIFARE Classic 1K, 4K, Mini等)。 You can check the official project page for

is a specialized Android application designed for low-level interaction with MIFARE Classic RFID tags. While newer versions like 4.3.1 are currently available on platforms like Google Play and F-Droid , many users specifically seek version 2.3.1 or similar legacy builds for compatibility with older Android hardware or specific firmware environments. Core Features of MIFARE Classic Tool

MIFARE Classic Tool 2.3.1 is a foundational application in the world of NFC and RFID security research. Its comprehensive, low-level features provide a direct interface to the inner workings of MIFARE Classic tags. While its legitimate uses—like backing up access cards or managing IoT devices—are immense, its existence also serves as a stark reminder of the inherent vulnerabilities in the still-widely-deployed MIFARE Classic technology.
