Biometric Systems: Zones Clocks and Biometric

Biometrics, such as attendance control, is useful in warehouses, schools, offices, state organizations, private companies and libraries regardless of size. In addition, controls, biometrics, have many applications such as registration of visitors, access control, door biometric fingerprint readers and even facial recognition scanners.

Biometric systems are devices that identify people by one or more physical characteristics. This is done through an automatic process and may involve scanning a fingerprint, eye, hand and even voice recognition. However, the welfare system, biometric, most popular is the fingerprint scanner. With this device, each time the employee arrives at work or out of it, put your finger on a reader who, using special software, verify that the new fingerprint scanner is based on a database, along with the identification of each employee. If this happens this time is recorded and that person can access a particular site.

Biometrics is used to attest that each person who enters a workplace, is who claims to be. When an employee is logged into a fingerprint scanner for the first time, the software records an image of your fingerprint and associates it with the identification number of that employee. The image taken measures the relationship of various points of a fingerprint and so you get different images of each employee.

Many schools already use biometric systems to have full information on each student, which helps parents and teachers quickly noticed student absences. It also implements a useful tool to prevent impersonation in examinations or tests. Examples of this can be seen in the U.S. and Britain, where several schools have installed fingerprint readers, such as anti-fraud mechanisms.

The use of biometrics in schools not only limited to anti-fraud systems, since it is also useful for the delivery of school lunches, for the loan of library material and even the use of lockers.
