Biometric systems utilize individual unique identification to verify specific characteristics of an individual to grant access to a system. The unique biometric identification makes duplication or alteration of information almost impossible. This has encouraged the acceptance of biometric technology and enabled the technology to evolve exponentially. Besides the benefits of security features promoted by the biometric system, reciprocally, biometric systems also have limitations that can cause problems. This paper reports on reviews conducted on articles with the aim to identify different types of biometric systems, the application domains, constraints, and limitations of existing biometric systems.
