What is a Biometric Time Attendance System?


A biometric time attendance system is a modern way to maintain attendance records through the use of iris scans or fingerprint scans. A biometric reader is usually placed at the entrance and exit of a building. Employees use their hands or eyes to enter or leave their place of work. There has been a substantial rise in the popularity of biometric systems due to its ability to track and monitor employees effectively and non-intrusively. Sensitive establishments are showing particular interest in this technology because of slim margin of error.

When employees turn up at their place of work, they press their hands against a device or look into a sensor. The device captures this data and sends it to a larger control system where it is processed. If the data proves the person at entrance is an employee, he or she is allowed to enter and the time of his or her entry is saved. The same method is used when an employee exits the premises. The device at the exit makes a note of the time of exit and sends to the same control system.

Human resource and account departments in companies find this data extremely useful as it provides information about attendance of employees, number of hours logged in by the employees and other relevant information related to the employee. This information is then used to calculate paychecks. The data also comes handy when the management wants to know about the performance of an employee.

In some cases the attendance system can be joined with biometric security devices. When this happens, the larger central system can provide real-time data on the location of an employee within a company premises. 

In companies using old attendance systems, a friend of an employee can login on behalf of his friend. This amounts to fraud. The company loses money by paying an absent employee. But buddy punching is near-to-impossible with biometric time attendance system. An employee has to be physical present.

Biometric devices are more than advanced spy devices that make companies super-efficient. They are useful in emergencies. If there is a fire, or an earthquake, rescue operations become relatively easier if a company knows how many employees were present at the time of disaster. This information can be life saving.
