IMPORTANT NOTES
Some important things are:
• The features this tool provides are very basic. There are no such
fancy things like saving a URL to an RFID-Tag with a nice looking
graphical user interface. If you want so save things on a tag,
you have to input the raw hexadecimal data.
• This App can NOT crack/hack
any Mifare Classic keys. If you want to read/write an RFID-Tag, you
need keys for this specific tag first. For additional information
please read/see Getting Started from the links section.
• There will be no "brute-force" attack
capability in this application. It is way too slow due
to the protocol.
• This app will NOT work on the following devices because
their hardware (NFC-controller) does not support Mifare Classic
( https://github.com/ikarus23/MifareClassicTool/issues/1 ).

    Tried writing to a sector 0 writable card using a HTC one. Unfortunately this fails, maybe incompatible card. Could you recommend any cards you have succesfully tested?

    Once you start the application it tells you it won't work cause the S3 is lacking mifare Clasic support. Would have been nice to know this before downloading and installing.
