I needed simple tool for testing and learning the Mifare and generally ISO14443A/B cards protocol for my thesis. I was inspired by RFIDiot.
However this one has very nice advantage it will not let you screw the AC bits, so making the card useless in result. It can import data to write from yaml,csv or purely binary file (usually for previously exported).
All needed requirements are in requirements.txt for your convience when using pip. Just use pip install -r requirements.txt.
Beside you need PCSCd daemon and libraries. On deb-based systems you just need to: apt-get install pcscd libpcsclite-dev libnfc
Enclosed in file.
