+
+ 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 or 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
+
+ v2.0 - Refactored to add I2C support from Adafruit_NFCShield_I2C library.
+
+ v1.1 - Added full command list
+ - Added 'verbose' mode flag to constructor to toggle debug output
+ - Changed readPassiveTargetID() to return variable length values
