[0064] At block 720, the user is instructed to move the scanning device in a certain direction. In some embodiments, the user is instructed to move the scanning device via the device itself. In some embodiments, the direction can be an alert, such as a tactile alert, a visual alert, or an auditory alert. Then, method 700 proceeds to block 730.

[0065] At block 730, the scanning device displays a scanning guide (such as scanning guide 400). In some embodiments, the scanning guide is displayed on the user interface of the scanning device. In some embodiments, the scanning guide can display an image captured by a camera on the scanning device, as well as an arrow indicating the direction in which the user should move the scanning device to fully capture the facial feature. In some embodiments, the scanning guide can be a graphical representation of the facial feature and include an arrow indicating the direction in which the user should move the device. Then, method 700 proceeds to block 740.

[0066] At block 740, the scanning device moves in the direction indicated by the scanning guide. Then, method 700 proceeds to block 750.

[0067] At block 750, multiple images of the facial feature are captured with a camera. In some embodiments, the camera is located on the scanning device. Then, method 700 proceeds to block 760.

[0068] At block 760, the multiple images captured by the camera are combined. In some embodiments, combining the images includes: stitching the images together based on the position indicated by a position sensor. Then, method 700 proceeds to block 770.
