Thank you d_stranz,

I have only 5 pieces classic 1K contactless Mi-Fare card that I bought from e-bay. There isn't any support page. I have only "http://www.nxp.com/documents/data_sheet/M001053_MF1ICS50_rev5_3.pdf" documentation. And there isn't any example.
I want to experiment with QT GUI. I am looking simple example tutorial sample for reading and writing using QT GUI.

Kind Regards,
