Studying the physical characteristics of a person such as your fingerprint, hand geometry, eye structure or voice pattern is described as Biometrics. This method of identification works by measuring unique human characteristics as a way to provide irrefutable proof of identity; for example finger or iris scanning or dynamic signature verification.
Various types of biometric systems are currently being used for real-time identification, the most popular are based on face recognition and fingerprint matching. However, there are other biometric systems that utilize iris and retinal scan, speech, facial thermo grams, and hand geometry. For some very high security operations HOA Technology Systems may advise on a twofold process that includes both biometric and card identification. All the biometric systems we install allow the biometric readers the ability to compensate for environmentally induced changes such as cuts, swelling, temperature, and dirt.
