Hi I don't know if this is possible because I have been searching for hours with no leads. I want to make a C# program on desktop that is connected to the ACR122u reader. I want to be able to read and store the NDEF message value as a string for processing. Is this even possible if so where do I begin?
Note: I have looked and examined the examples supplied with the ACR122u reader but none have worked for me or even displayed the message I stored from a third part application.
According to this website that reader is PC/SC compliant. You should be able to access it via that interface. See here for an example. Here is a highly-rated CodeProject article along the same lines, except it features a wrapper for the complex PC/SC commands.
