+Arduino RFID Library for MFRC522
+
+Read a card using a mfrc522 reader on your SPI interface on your Arduino
+* Pin layout should be as follows (on Arduino Uno):
+* MOSI: Pin 11 / ICSP-4
+* MISO: Pin 12 / ICSP-1
+* SCK: Pin 13 / ISCP-3
+* SS: Pin 10 (Configurable)
+* RST: Pin 9 (Configurable)

+TODO:
+
+Create Examples:
+- Read more stuff than the serial number
+- Write to a card
+- Do some ethernet stuff (with an ethernet module)
