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.
The first block of the first sector of an original
MIFARE Classic tag is read-only i.e. not writable. But there
are special MIFARE Classic tags that support writing to the
manufacturer block with a simple write command. This App is able to
write to such tags and can therefore create fully correct clones.
However, some special tags require a special command sequence
to put them into the state where writing to the manufacturer block is possible.
These tags will not work.
Remember this when you are shopping for special tags!
This app will NOT work on some devices because
their hardware (NFC-controller) does not support MIFARE Classic
( https://github.com/ikarus23/MifareClassicTool/issues/1 ).
