Mifare Classic Tool 2.3.1 -

(Based on standard changelog patterns for recent MCT releases)

Mifare Classic Tool (MCT) is an Android application designed to read, write, and analyze MIFARE Classic RFID tags. It is intended for security researchers, system administrators, and electronics enthusiasts to audit access control systems or manage RFID hardware.

Version 2.3.1 is a maintenance release focused on stability improvements, UI bug fixes, and compatibility updates for modern Android versions.

Since MCT is open-source and free, it can be obtained via the following methods:

Fingerprints (SHA-256): Verify the signature of the APK if downloading manually. (Checksums are usually found on the official GitHub release page).

Using MCT 2.3.1 to clone a transit card for free rides, break into a building you do not own, or duplicate a hotel key without authorization is wire fraud or theft of service in most jurisdictions (Computer Fraud and Abuse Act in the US; Computer Misuse Act in the UK).

At its core, MIFARE Classic Tool (MCT) 2.3.1 is an Android application designed to read, write, and analyze MIFARE Classic RFID tags. Unlike basic NFC apps that only read a UID (Unique Identifier), MCT acts as a full-fledged Swiss Army knife for 13.56 MHz RFID.

While MCT is powerful, it is bound

MIFARE Classic Tool (MCT) version 2.3.1 is a specialized Android application designed for interacting with MIFARE Classic RFID tags using a smartphone's built-in NFC hardware

. While it is a powerful utility for hobbyists and security researchers, its effectiveness is strictly tied to the hardware limitations of the phone and the security vulnerabilities inherent in the MIFARE Classic standard. Core Functionality

The tool acts as a portable reader/writer that allows users to: Read and Write

: Access data across the 16 sectors of a MIFARE Classic 1K card, provided the correct access keys (Key A or Key B) are known. Analyze Data

: View the hexadecimal structure of the card, including the manufacturer block (Sector 0), which contains the unique identifier (UID). Key Management

: Create and edit "key files" (dictionaries) to perform dictionary attacks against tags with default or common keys. Value Blocks mifare classic tool 2.3.1

: Manipulate "Value Blocks" typically used for credit or counting systems in transit and access cards. Suprema Knowledge Base The Security Context

MIFARE Classic is an older technology (13.56 MHz) now considered cryptographically broken

. MCT leverages this by allowing users to interact with tags that use weak or default encryption. Vulnerability : Many systems still use default keys (e.g., FFFFFFFFFFFF

), which MCT can easily identify using its built-in dictionary.

: 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

: Not all Android phones can use MCT. The phone's NFC chip must be manufactured by

to support the proprietary MIFARE Classic "Crypto1" protocol. Many modern phones using Broadcom NFC chips cannot communicate with these tags at all. Hardened Tags : It cannot bypass modern security like MIFARE Plus , which use AES encryption. Where to Find It

As an open-source project, the most reliable versions and documentation are hosted on

. Version 2.3.1 included various stability fixes and updated key dictionaries for newer tag types. Do you have a specific card

Deep Dive: MIFARE Classic Tool (MCT) MIFARE Classic Tool (MCT) is a powerful, low-level Android application designed for reading, writing, and analyzing MIFARE Classic RFID tags. Developed by Gerhard Klostermeier, it is a specialized utility for users with a basic understanding of MIFARE technology who need to interact directly with raw hexadecimal data. Core Functionality

MIFARE Classic Tool provides a comprehensive suite of features for managing and interacting with RFID tags:

Tag Reading and Writing: Read data from MIFARE Classic tags and write new data block-by-block.

Cloning Capabilities: Create exact duplicates by writing a "dump" of one tag onto another. It also supports writing to the "manufacturer block" (Block 0) of special "magic" tags to clone unique IDs (UIDs). (Based on standard changelog patterns for recent MCT

Dictionary-Based Key Management: Instead of cracking keys, MCT uses a "dictionary attack" method. You can create key files (dictionaries) containing known keys, and the app will try to authenticate with every key in the file to read as many sectors as possible. Data Analysis Tools:

Diff Tool: Compare two different tag dumps to see differences.

Value Block Decoder: Decode and encode MIFARE Classic "Value Blocks" and access conditions into readable formats or tables.

Multiple Formats: View tag data as highlighted hex, 7-bit US-ASCII, or as integers.

External Reader Support: The app can interface with external NFC readers like the ACR 122U. Technical Limitations & Security While robust, the tool has several specific constraints: MIFARE Classic Tool - Apps on Google Play
