doing some #python tests GetCard SendCommand for ISO/IEC 14443 smartcards.
- python run and trace in Quest software as well as RGPA software. disadvantage missing debugging comf
- so moved to VS Code with python and Keolabs lib python file
- searching for implementation file and possible dlls for c# integration
- Poller0 PCD proximity coupling device and PICC
- challenge is to set up full python setup outside of delivered Quest. API functions full details?
