+
+    This example will wait for any ISO14443A card or tag, and
+    depending on the size of the UID will attempt to read from it.
+
+    If the card has a 4-byte UID it is probably a Mifare
+    Classic card, and the following steps are taken:
+
+    Reads the 4 byte (32 bit) ID of a MiFare Classic card.
+    Since the classic cards have only 32 bit identifiers you can stick
+	them in a single variable and use that to compare card ID's as a
+	number. This doesn't work for ultralight cards that have longer 7
+	byte IDs!
+
+    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!
+
+This is an example sketch for the Adafruit PN532 NFC/RFID breakout boards
+This library works with the Adafruit NFC breakout
