M Tools is the first application globally capable of directly reading and charging your Mifare Classic and Ultralight cards.
Additionally, it is the pioneering mifare card charger compatible with NFC, PN53X, and ACR122U.
With M Tools, users can compare and analyze data rules effectively.
It is essential to understand the keys and data rules beforehand.
Features include:
1.Direct reading and writing to sectors.
2.Automatic saving of keys when they are modified.
3.Data comparison with highlighted displays.
4.Emulation calculations.
5.Support for multiple cards and rules.
6.Crc8 and Crc16 calculation capabilities.
User Guide:
1. **Preparation**
Know the **key** and **data rules** of the target Mifare card beforehand. This is a prerequisite for operation; without this information, read and write operations are impossible.
2. **Device Connection**
Ensure your device supports NFC, PN53X, or ACR122U card readers. Enable the corresponding function and hold the Mifare card close to the sensing area.
3. **Core Operations**
- **Read/Write Sectors**: Directly read and write sectors on the card. After modifying the key, the app will automatically save the new key.
- **Data Comparison**: Import or read data from two cards for comparison. Differences will be highlighted for quick analysis.
- **Calculation Function**: Use the built-in CRC8 and CRC16 calculation tools to perform data verification; you can also perform simulation calculations to verify rules.
4. **Multi-Card Management**
Add different types of Mifare cards and match them with corresponding operation rules to achieve multi-card classification management and batch operations.
