+ * MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
+ * The library file MFRC522.h has a wealth of useful info. Please read it.
+ * The functions are documented in MFRC522.cpp.
+ *
+ * Based on code Dr.Leong   ( WWW.B2CQSHOP.COM )
+ * Created by Miguel Balboa (circuitito.com), Jan, 2012.
+ * Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
+ * Released into the public domain.
+ *
+ * Sample program showing how to read data from a PICC using a MFRC522 reader on the Arduino SPI interface.
+ * Pin layout should be as follows:
+ * Signal     Pin              Pin
+ *            Arduino Uno      MFRC522 board
+ * -----------------------------------------
+ * Reset      9                RST
+ * SPI SS     10               SDA
+ * SPI MOSI   11               MOSI
+ * SPI MISO   12               MISO
+ * SPI SCK    13               SCK
+ *
+ * The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com.
