How Biometric Technologies Work

Biometric technologies capitalize upon unique, permanent, and scannable human characteristics. A unique characteristic is one that no other person shares. This characteristic should also remain the same over time, and be reliably collectable using a sensor. As much as possible, biometric technologies focus upon these types of human traits.
All biometric devices take a number of measurements from an individual then digitally process the result of these measurements and save this representation of the individual’s traits into a template. Templates are then stored in a database associated with the device or in a smartcard given to the individual. This is called enrollment.

Return on Investment in Biometric Time Clock Installations

Biometric time clocks, which are used to record employee start and end times, are popular in organizations where security is an issue, or where employees may falsely record their time worked. Because biometric technology is more expensive than other forms of time clock identification, such as magnetic badges or personal identification numbers, it is important to evaluate the potential return on investment should biometric devices be installed. In service environments where employees punch in and out to work, return on investment can be considerable because biometric devices virtually eliminate the ability of employees to “buddy punch.”

Be sensitive to the concerns of employees.

When considering the purchase of biometric time recorders it is important to address the privacy concerns of employees. For example, explain to employees that a finger or hand reader does not store or recognize employee fingerprints—it uses hand or finger measurements to create a template for the employee. These measurements are used only for in-company authentication and security access. They cannot be used to recreate biometric data such as a person’s actual fingerprint.
Furthermore, you can emphasize that employee privacy is enhanced with biometric time clocks. When an employee accesses his benefit time balances using a biometric time clock, no other employee is privy to these records, increasing the security of his personal information.
