How do i interface opencv code to arduino?

i am doing a project on access control using OPENCV , arduino and rfid. The user has to swipe the card and have his/her face detected by the camera to verify its who they claim to be before access is granted.
the rfid cards are working and also the fece detection part.So how do i join the two to have my complete project?

Although I have never used OPENCV, may I assume that the RFID tag will either be accepted or denied? If so create a VAR-"ible" that will store the value of "Accepted" OR "Denied". I will also assume that you can do the same facial detection, Via OPENCV.

Then couldn't you just make a "AND" statement; Have it trigger the deadbolt and be done with it?
