+
+    This is a library for the Adafruit PN532 NFC/RFID shield
+    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 I2C to communicate
+
+    Adafruit invests time and resources providing this open source code,
+    please support Adafruit and open-source hardware by purchasing
+    products from Adafruit!
+
+    @section  HISTORY
+
+    v1.3  - Modified to work with I2C
+
+    v1.1  - Added full command list
+          - Added 'verbose' mode flag to constructor to toggle debug output
+          - Changed readPassiveTargetID() to return variable length values
