-/*! 
-    This example will attempt to connect to an ISO14443A
-    card or tag and retrieve some basic information about it
-    that can be used to determine what type of card it is.   
-   
-    Note that you need the baud rate to be 115200 because we need to print
-    out the data and read from the card at the same time!
-
-    To enable debug message, define DEBUG in PN532/PN532_debug.h
