What are the classifications of biometric access control systems? | HFSecurity
Traditional access control systems generally use IC cards, magnetic stripe cards, ID cards, while biometric access control systems use a variety of different biometric identification, from the security point of view, people tend to use biometric identification with higher security.Installing face recognition on traditional access gates, which is now obsolete, face gates use the person's own characteristic information for verification, which is a great improvement in efficiency and security.Face recognition is based on the biometric features generated by combining a person with a specific form such as a photo or video.In recent years it has been gradually discovered that it will be a trend to use some physical features unique to the human body such as fingerprints, palm prints, iris, for identification and verification. Face unlocking is one of them.With the development of technology, the application scope of biometric technology is also expanding, and many biometric technologies are beginning to be applied to the security field, such as face time and attendance system, fingerprint access control system, iris access control system, etc. Nowadays, biometric features such as face, fingerprint and iris have been widely used in various fields of society.
