IMPORTANT NOTESSome important things are:
• The features this tool provides are very basic. There are no suchfancy things like saving a URL to an RFID-Tag with a nice lookinggraphical user interface. If you want so save things on a tag,you have to input the raw hexadecimal data.
• This App can NOT crack/hackany Mifare Classic keys. If you want to read/write an RFID-Tag, youneed keys for this specific tag first. For additional informationplease read/see Getting Started from the links section.
• There will be no "brute-force" attackcapability in this application. It is way too slow dueto the protocol.
• The first block of the first sector of an originalMifare Classic tag is read-only i.e. not writable. But thereare special Mifare Classic tags that support writing to themanufacturer block with a simple write command. This App is able towrite to such tags and can therefore create fully correct clones.However, some special tags require a special command sequenceto 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 becausetheir hardware (NFC-controller) does not support Mifare Classic( https://github.com/ikarus23/MifareClassicTool/issues/1 ).You can find a list of unsupported devices here:https://github.com/ikarus23/MifareClassicTool#general-information
