· Behavioral Biometric Scanners

These read signatures using the velocity of the sign pressure of the sign and velocity of the sign that are exclusive for each human

· Auditory biometric devices

These devices use the speakers' voice to analyze and authenticate identity so the user can be given access control authentically

· Olfactory Biometric sensors

These devices scan and analyze the odor of a human to distinguish one from another and authenticate identification of an individual

What are the uses of the biometric scanners and fingerprint readers?

Work environment

Widespread proxy punching has necessitated the need of installing finger print recognition devices like Morpho biometric fingerprint scanner which have proved effective in controlling fraud in attendance and working hours

Immigration

Demand for air travel has necessitated airports to implement a sound technology which is fraud proof and the biometric devices like IRIS recognition device that will quickly identify the person and allow him to pass. This will reduce queues forming and inconveniencing airport work.
