Serial communication with Windows Phone 8

Question

Does windows phone 8 support serial communication?
I am working on my graduation project now. I plan to use a phone to communicate with a RFID　device via a serial port.

I get three solution.

1. Use Windows Mobile 6
2. Use Windows Phone 7 or 8
3. Use Android

Personally, I prefer 2. But I am not sure whether Windows Phone support serial communication or not. If not, is there any solution?

Answer 1

You can't do this with windows phone 7, but with windows phone 8 you have access to the Bluetooth API so you could try serial over Bluetooth.

Answer 2

With Android, you can use serial communication over USB cable. It depends on your requirements but setting up a USB connection is sometimes easier than managing a bluetooth connection.

It is up to you.
