title: How can read/write to my ACR122U NFC/Smartcard reader?
body: <p>I bought a GoToTags ACR122U NFC/smartcard reader but I am really disappointed with it. Their free windows application simply locks you into their propietary stuff. I want to write my own application to read/write NFC tags.</p>
  
  <p>I have been trying to find an SDK that I can use with managed code (C#) but no luck yet. Somewhere I found ACR122U sample applications with "SDK" but none of the sample apps work because NONE has a reference to a DLL that can be used to access it. Only their C++ code seems to have an acr122.dll in their root directory but it is not possible to import it as a reference in my C# application.</p>
