+    This is a library for the Adafruit PN532 NFC/RFID breakout boards
+    This library works with the Adafruit NFC breakout 
+    ----> https://www.adafruit.com/products/364
+    
+    Check out the links above for our tutorials and wiring diagrams 
+    These chips use SPI to communicate, 4 required to interface
+    
+    Adafruit invests time and resources providing this open source code,

+
+    @section  HISTORY
+
+    v1.1  - Added full command list
+          - Added 'verbose' mode flag to constructor to toggle debug output
+          - Changed readPassiveTargetID() to return variable length values
