I am doing a project based on RFID interfacing with atmega16.
Here's the circuit diagram

I have to buy RFID. What should I ask in the electronics store and what are the necessary things that I should check with the RFID while buying?
Also I see we use two db9. The one end of db9 which has the wires will be connected to max232 and the other end consists of holes. So how do I connect two db9?
