Hand scanner
Hand scanner
A hand scanner is an input device that captures an image of a user’s hand and converts it into a digital signal for authentication or other purposes. It uses advanced imaging technology to accurately capture the unique characteristics of an individual’s hand, including the veins, wrinkles, and shape.
What does HAND scanner mean?
A hand scanner, also known as a palm scanner or hand geometry scanner, is a biometric security device that identifies individuals by the unique shape and other physical characteristics of their hands. Hand scanners are commonly used in access control systems, time and attendance systems, and other applications where secure identification is required.
Hand scanners work by capturing a digital Image of the user’s hand and then extracting and analyzing the data into unique features of the user’s hand. Upon matching, it compares these features to a database of enrolled users to verify their identity. These unique features include the shape, size, and curvature of the hand, as well as the length and thickness of the fingers and palms.
The technology relies on the fact that no two hand geometries are exactly alike, not even between identical twins. This makes hand scanning a highly accurate and reliable form of biometric identification. It is also a very safe and hygienic method, as it does not require any contact between the user and the device.
Applications
Hand scanners are used in a variety of applications, including:
- Access control: Hand scanners can be used to control access to secure areas, such as buildings, rooms, and computer systems. They can also be used to Track the movement of people within a facility.
- Time and attendance: Hand scanners can be used to track employee time and attendance. They can also be used to prevent buddy punching, which is when one employee clocks in for another employee.
- Identity Verification: Hand scanners can be used to verify the identity of individuals for a variety of purposes, such as banking, voting, and law enforcement.
- Medical applications: Hand scanners can be used to identify patients in hospitals and clinics. They can also be used to track the progress of patients during their treatment.
History
The first hand scanner was developed by the United States Army in the 1980s. The device was used to identify soldiers in the field. In the 1990s, commercial hand scanners were developed and began to be used in a variety of applications.
Today, hand scanners are a well-established and widely used biometric security technology. They are used in a variety of applications, from access control to time and attendance to identity verification. Hand scanners are a safe, convenient, and accurate way to identify individuals.
