RFID/NFC shield
i set up my arduino with this shield and am wondering how to simply write messages to the mifare tags and then read them with the same shield. i am new to programming and not sure how to use commands in the library. any tips or suggestions would be very appreciated. thank you

Re: RFID/NFC shield
I have and got all the examples working, but i dont know where to start in learning the commands so that i can program my own code for this shield.

Re: RFID/NFC shield
The examples have "examples" of the commands. If you want more info on what they do check out the .cpp and .h files in the library for the prototypes.

You can read them with a text editor or download a program that knows how to format c++ syntax http://notepad-plus-plus.org/
