-    This example attempts to format a clean Mifare Classic 1K card as
-    an NFC Forum tag (to store NDEF messages that can be read by any
-    NFC enabled Android phone, etc.)
-
-    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
