A wide range of biometric sensors & detectors are available to consumers for security and access control management. Biometrics refers to methods for recognizing individual people based on unique physical and behavioral traits. Physiological biometrics is one class of biometrics that deals with physical characteristics and attributes that are unique to individuals.
*Uses:
Biometric sensors/detectors are useful in several industries as well as consumers who can put them to use in access control and identity access management and information technology applications. Sensors and detectors are semiconductors (meaning its electric conductivity is in between a conductor and an insulator) which use algorithms to process images from the user's physical characteristics. *How do they work?
Biometric sensors work by producing electrical currents when they scan a user's physical characteristic. Many physical characteristics may be scanned by a biometric sensor including eyes, fingerprints, or DNA. Sensors contain an analog to digital converter enabling it to digitize the image and store the digital information in memory so that it can verify the user next time he or she needs to authenticate their identity.
