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 ).
