A single image from a camera ( 14 ) is captured of an individual ( 40 ) seeking entry through a door held by a door latch ( 24 ). An image processor ( 16 ) looks for and locates a tag ( 42 ) worn by the individual ( 40 ) in the image and reads an identification (ID) code from the tag ( 42 ). A comparator ( 20 ) compares this ID code with ID codes in an identification database ( 22 ) to find a match. Once a match of ID codes is found, the image processor ( 16 ) looks for and locates a face ( 44 ) of the individual ( 40 ) in the image and extracts facial features from the face ( 44 ). The comparator ( 20 ) compares the extracted facial features with facial features associated with the matched ID code, from the identification database ( 22 ), to find a match. Once there is a match of facial features, the door latch ( 24 ) is released.
