Each person has unique characteristics that are determined by genes. Biometric identification takes advantage of these characteristics and uses unique human physical characteristics to identify an individual.
Examples of characteristics that identify humans may be fingerprint, retina scan, voice recognition and signature details. By maintaining a database of one or more of these characteristics, current software is able to compare a produced identity feature with the features on file. Organizations that need advanced security have these security programs that allow employees to enter secure aresa after producing matching characteristics at the organizational gateway.
Airports, hospitals and federal government offices are frequent users of this type of technology. Frequently, an identification card system will be combined with the biometric system to meet the requirements of the organization’s security system.
