Setup the hardware

You will need to connect 6 pins from the reader to the ICSP pins in the Arduino Uno and another pin to Digital pin 9

Arduino RFID Pins

MISO (Master In Slave Out) - The Slave line for sending data to the master
MOSI (Master Out Slave In) - The Master line for sending data to the peripherals
SCK (Serial Clock) - The clock pulses which synchronise data transmission generated by the master and one line specific for every device
SDA (SS) (Slave Select) - the pin on each device that the master can use to enable and disable specific devices

NOTE: It is better to solder the pins to reader in order to ensure it doesn't lose connectivity. If this happens the reader will need to be reset.

Setup the library

Download the RFID library from here
Extract it
Copy it to your Arduino folder and reopen the IDE
Now you should see this:
