1. An iris scanning device, comprising:
a gimbal having a mirror mounted thereon;
a camera;
control circuitry configured to orient the gimbal having the mirror mounted thereon such that an image of an eye of a user of the iris scanning device is captured, wherein the gimbal is oriented such that an angle between the eye of the user and the mirror mounted on the gimbal causes the image of the eye of the user to be captured by the camera; and
a facial feature detector configured to:
identify features of the eye of the user from the image of the eye of the user; and
determine whether the image of the eye of the user satisfies criteria based upon the features of the eye;
wherein the control circuitry is further configured to adjust the orientation of the gimbal having the mirror mounted thereon based upon the features of the eye when the image of the eye of the user does not satisfy the criteria, wherein the mirror mounted on the gimbal is oriented to cause a second image of the eye of the user to be captured by the camera upon the orientation being adjusted based upon the features of the eye.
