Arduino Fio to RFID ID-12

Hello,

Can someone verify my diagram of connecting the Arduino Fio with an ID-12 RFID Reader? I figured that using a Logic Level Converter is the proper way to do it, but Im not sure if I should have a DC-DC step up board between the two to provide power to the ID-12 or if the LLC can step up the voltage as well.

Your ID-12 requires 5V, as does the level shifter, so you will need the DC/DC converter if you want to use them with a 3.3V power source.

Thats what I thought. Thanks.
