Which example code are you talking about? and where are they provided?
The reader came along with its own software using which I was able to detect the tags. But they didnot provide any library for Arduino neither did they provide any example codes.
I did look at some of the example codes of MRC522 by miguelbalboa and some othe MRC522 libraries at github, also the library of SeeedRFID.. but all say that it works for RFID of 125 kHz. So I was wondering would they work for 865 Mhz too or not.
If you mean something else please say.
