**IMPORTANT CONSIDERATIONS**
* The tool provides fundamental features. It doesn't include advanced functionalities such as URL saving with a graphical interface. Users are expected to input raw hexadecimal data for writing.
* This app does *not* crack or hack MIFARE Classic keys. You *must* possess the correct keys to read or write to a specific tag. Refer to the 'Getting Started' section for more information.
* Brute-force attacks are *not* supported due to protocol limitations.
* The first block of the first sector on genuine MIFARE Classic tags is typically read-only. However, special 'magic tag gen2' tags allow writing to the manufacturer block. This application supports writing to these tags for complete cloning. note that some special tags require specific commands to enable writing to the manufacturer block, and these may not be compatible.
* This app may *not* function on all devices due to NFC conTroller limitations (https://github.com/ikarus23/MifareClassicTool/issues/1). A list of unsupported devices can be found here: https://github.com/ikarus23/MifareClassicTool#general-information.
