RFID Door Lock [some questions]

Hi everyone, in the fall, I will be going to college, and I would like to make a device to open my dorm room with an RFID tag. I have a few questions. First, can I buy the USB reader from parallax, and hook it up to a propeller protoboard USB with a usb cable, or do i need to buy the TTL version? (I would rather buy the USB, for ease of use connecting it to a computer.) Second, will I have difficulties reading through an inch of wood? Third, if I use a servo to pull the door handle, will it burn out if it stalls for a few seconds when the door handle is in the open position?

Thanks in advance

    1. no
    2. possibly but you would be better off placing it as close as possible.
    3. probably but it might take quite a while. add a spring to allow the servo to get to its resting position without stalling.
