How do Biometric Time and Attendance Systems Work
View Full Size

Biometric time and attendance systems have become popular in the business world today when it comes to tracking employees and their attendance. Biometric systems are easy to use, easy to install and track data regarding employees for management to analyze.

The biggest advantage of these systems is that they prevent employees from clocking in for one another. Previous methods included a timeclock, a sign-in sheet and swiping an ID card. These systems create more of an honor system for employees to follow, reducing employee time theft.

How Biometric Systems Work

Biometric time and attendance systems use the fingerprints of employees to verify who is actually clocking in and clocking out of work each day. The system scans the finger of the employee, coordinates are determined and then the system maps the endpoints and intersections of the fingerprint.

These are then referenced against what is in the system from the employee. If an employee has not been entered into the system, he or she will not be able to use the biometric system to clock in and out of work each day.

Biometric Systems are Safe

Many people worry that biometric systems can be hacked or logged into by outside entities, such as law enforcement agencies. This is not the case. A biometric absence tracker is completely safe and secure. It can only be used, and data accessed, by the company that uses the system. These systems can typically only be used for tracking time and attendance and providing access to employees to certain areas of the building.

There is no personal information used in the biometric system except for the employee’s fingerprint and his or her employee ID number. The employee’s social security number and other personal information, such as birthdate, are not used by the biometric system. This is what makes the system so secure. Even if it is hacked, which is highly unlikely, there is no personal information worth stealing.

Fingerprints are Deleted from the System

To make a biometric system even more secure, the system deletes fingerprints from the system. When a new employee is entered into the system, the software scans the fingerprint to create a group of coordinates. The fingerprint itself is then deleted to protect the security and identity of the employee. The next time the employee uses the touchscreen on the biometric system to clock in or out, the coordinates on file are matched with the fingerprint on the screen to verify the employee’s identity.

Restrict Employee and Non-employee Access

Another major benefit of using time & attendance systems is that they restrict employee and non-employee access to certain areas of your organization. For example, if a group of employees are not supposed to access a certain area of your building, their fingerprints will be flagged in the system so they cannot enter.

This makes the building more secure from intruders or visitors who simply want to wander around the campus. They will not be able to access the restricted areas even if they attempt to use their fingerprint to gain access. Management will be able to assign and revoke access to individual employees using the software, much like using a keycard or keyfob.

Two Technology Types Used

Biometric absence management software uses two types of technology; image-based and capacitive. Image-based technology is when the software takes a picture of the fingerprint using a scanner to create the biometric template for each employee. Capacitive technology is when the software uses electronic pulses on a touchscreen to feel the ridges on the fingerprints to make the template of endpoints and merge points.

Mobile Capabilities

Biometric systems have mobile capabilities, which means employees who are out of the office can still clock in and out while on the road. This is perfect for companies where employees are constantly in company vehicles making deliveries or house calls for repairs. You will be able to track their time on the job and make sure the employees are not abusing the timeclock since they are away from management’s eyes.

Recap of Biometric System Benefits

We have put together a list of some of the best benefits of using biometric systems. These benefits include the following:

  • Easy to use
     
  • Fast way to clock in
     
  • Stronger security measure
     
  • Prevents theft of time
     
  • Accurate detail recording
     
  • User friendly for all employees
     
  • Easily integrated into payroll, accounting and billing systems
     
  • Saves time when clocking time
     
  • Saves money by accurately tracking time
     
  • Prevents buddy punching, early punching or late punching by employees
     
  • PTO Tracking Software for compliance

When it comes to tracking paid time off, biometric systems are perfect for the job. PTO tracking software that uses biometric tracking makes it easier to track when employees are due paid time off and how many more hours the employee has to work before earning PTO.

Biometric time and attendance systems are easy to use, easy to install, user friendly and help companies save money. They do not pose a security threat to employees’ personal data, while ensuring there is no abuse of company time.
