How do you write / read to a smartcard?

Question

Is there an Open Source library for writing and reading data in C# from a smartcard using a smartcard reader? My smartcard model is mifare1k and my reader is ucr122u.

Solution 1

Check out Daniel Müller's pcsc-sharp, https://github.com/danm-de/pcsc-sharp

works very well for me on windows and mono.

Solution 2

I know this is an old question but you might want to PCSC-Sharp which is

PC/SC wrapper classes for .NET, written in C#. The package contains classes to access the Personal Computer/Smart Card Resource Manager using the system's native PC/SC API. Implements partial ISO7816 support. The library is written to run on both, Windows and Unix (Linux with Mono using PCSC Lite).

The project is on GitHub: https://github.com/danm-de/pcsc-sharp
