  4. Sign your name using a marker.

    Take a hite piece of paper or index card and sign your name using a black marker. Markers with a thick head usually work best and will be picked up more easily by the camera. Make sure the check box in the lower left corner is selected so that you don't have to repeat this step again in the future.
