<b>IMPORTANT NOTES</b>

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 <i>NOT crack/hack</i>

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 <i>Getting Started</i> from the links section.

• There will be <i>no "brute-force" attack</i>

capability in this application. It is way too slow due

to the protocol.

• The first block of the first sector of an <b>original</b>

MIFARE Classic tag is <b>read-only</b> i.e. not writable. But there

are <b>special</b> 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 <b>special command sequence</b>

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 <i>NOT</i> work on some devices because

their hardware (NFC-controller) does not support MIFARE Classic

( https://github.com/ikarus23/MifareClassicTool/issues/1 ).

You can find a list of unsupported devices here:
