Face scanner is a biometric device that uses unique patterns to scan human faces. With the help of face scanner, organizations can protect sensitive data and locations from being accessed by an unauthentic user. Face scanner scans the human face and then transfers the image directly to the memory and a tiny processor in the device.
After scanning the image, face scanner sends it to an image processing device such as computer in order to examine whether the person is a legitimate user and has appropriate rights to access the device. If not, face scanner denies the access. Face scanner is capable of scanning the shapes of eyes, chin, jaw edge, thickness of lips, width of mouth, structure of cheek bones, etc. quite intensely.
