Important Notes

• The features provided by this tool are very basic. There are no additional features like saving a URL to an RFID tag with a graphical user interface. If you want to store information on a tag, you must input the raw hexadecimal data.
• This App does not have the ability to crack or hack any MIFARE® Classic keys. In order to read/write an RFID tag, you need specific keys for that tag. For more information, please refer to the "Getting Started" section in the provided links.
• This application does not support brute-force attacks. The protocol involved makes it too slow.
• The first block of the first sector of an original MIFARE® Classic tag is read-only and cannot be written to. However, there are special MIFARE® Classic tags (aka magic tag gen2) that allow writing to the manufacturer block with a simple write command. This App can write to such tags and create fully functional clones. However, certain special tags require a specific command sequence to enable writing to the manufacturer block. These tags will not work unless the correct sequence is used. Keep this in mind when shopping for special tags.
• This app may not work on certain devices if their NFC-controller hardware does not support MIFARE® Classic. For a list of unsupported devices, refer to: https://github.com/ikarus23/MifareClassicTool#general-information
