Face Recognition Based Attendance System

Face Recognition Based Attendance System is The New Thing

Face Recognition Based Attendance SystemBeing watched and/or monitored is a legitimate fear for many people. This is why facial recognition is slow to be accepted and welcomed in many industries. One industry or field of work that would benefit the most out of facial recognition though, is that of attendance systems. The applications of Face Recognition Based Attendance System could be found in Schools, offices, events, and many others.

Most of us remember attendance at schools as the tutor calling out our names/registered numbers and us yelling back “PRESENT, MA’AM!”. All of that could soon change with the introduction of facial recognition in these systems.

How Face Recognition Based Attendance System Works And Advantages of Face Recognition Based Attendance System

How Face Recognition Based Attendance System Works And Advantages of Face Recognition Based Attendance SystemAs you may already know, facial recognition systems need a database or a pre-recorded data set to compare captured images and identify faces.

A recent report out of China stated that a school has installed facial recognition technology in its classrooms to monitor students’ behavior (Source: BusinessInsider).

In the same way, these cameras could be used to identify students and record their attendance in a class. With photos submitted to schools for various forms and documents, the students’ faces could be added to data sets to record their attendance in the respective classes.

Most offices and government buildings use biometric systems for logging in work hours and restricting access to only those people that are permitted. Although facial recognition is now being implemented in many countries for this purpose, they still largely rely on fingerprint sensors because of the lower chance of duplication and fraud. The downside to this is that recording a fingerprint is a task that requires relatively more effort.

By far the most interesting implementation of facial recognition in attendance systems is that of event attendance. The deployment of this system poses many benefits, especially for large events. Currently most events such as large corporate conferences and music concerts still largely rely on tickets, passes, and scanning of barcodes.

When audience numbers hit the late hundreds and even the thousands, the inefficiency of current systems begin to show. Checking tickets and scanning barcodes is a process that can take time depending on numerous variables.

Introducing facial recognition would cut down these inefficiencies since most modern facial recognition systems can perform the task in under two seconds. It is just a matter of collecting images of attendees at the time of issuing event passes.

This would also reduce the instances of ticket reselling as well as stolen or lost tickets being used by individuals that are not the official purchasers of said tickets.

Like most pieces of tech, the system does have its drawbacks as well….

Disadvantages of Facial Recognition in Attendance Systems

Disadvantages of Facial Recognition in Attendance Systems

  • Image quality

The quality of the reference image plays an important role in the identification process. If the resolution of the said image is not high enough, it can cause cameras to be tricked into believing that the person being scanned is not the same as in the photo. An easy solution is to ensure that both the reference images and scanning are performed by similar cameras.

  • Storage

Depending on the quality of the input data, a system would need an appropriate amount of storage. This could be troublesome if the data collected is of high quality and requires large amounts of storage space especially for events with a large expected attendance.

  • Angles

Many non-premium facial recognition systems cannot account for faces that are captured at angles other than straight into the capturing camera. The disadvantage of this is that it makes the attendance marking process slower and less efficient.


After what is said and done, face recognition based attendance system can massively benefit many types of industries. The amount of time saved and the elimination of human error makes for a more effective process. At FaceX, we constantly look to develop the best in facial recognition technology for industries of all types. This is only the beginning for facial recognition and we believe that we can achieve much more.
