how face recognition attendance system work?

Author: huifan   Time: 2021-10-20

For a long time, companies have relied on a number of traditional methods to maximize employee productivity. Until recently, the only option was essentially a manual time and attendance management system. Employees had to fill out paper work schedules that recorded their time worked. While this tracking system was widely used, it lacked flexibility, led to inaccurate and falsified timesheets, and often resulted in human error. Among all the biometric technologies that are already in use on the market or already being researched, face recognition attendance system  is an ongoing research topic in the field of computer vision, and its non-contact recognition technology has made a very significant contribution during the epidemic. The market is now flooded with modern solutions, but facial recognition-based time and attendance systems outweigh the expense due to their accuracy and ease of installation. In this article, we will focus on the best ways to automate attendance monitoring systems, with a special focus on the benefits of facial recognition technology
How to automate time and attendance management with facial recognition technology
A face recognition based  attendance system is an application that performs two main tasks - identifying a person based on key parameters and verifying his identity and authorization using a database. This technology combines artificial intelligence and machine learning to create a sophisticated solution.
Face recognition systems vary in terms of functionality and features, but the process of automating a system using face recognition software typically requires the same basic steps.

First, place the camera in the right position and start playing the video. If possible, use motion to activate the camera. This will prevent the continuous stream of video from overloading the face recognition server. The camera should be placed in such a way that the lens gets enough light and the user looks into the camera. If the user's face cannot be seen in its entirety, the camera should have as clear a resolution as possible.
Next, you need to split the video into frames or separate images. Ideally, if we want to send photos to the system for face recognition, we need to manually improve the quality of the photos to ensure that all our facial information is in the photo, an action we can easily do in the camera adjustment。 To ensure the accuracy of recognition, you can provide the status of the same person in different expressions and submit it to the server - if the server decides that the results of the same face are different, there may be an error.. Then you'll know you need to adjust your camera or other settings.
What tools can you use?
There are many tools on the market, each one ideal for different specific needs. In general, cloud-based platforms are not the best choice for facial recognition-based time and attendance management systems because they are not fault-tolerant in the event of an Internet outage. You should also be aware that implementing a system using free libraries takes a long time, requires machine learning skills, and is difficult to scale. With these points in mind, we have compiled a list of ideal facial technology software for you to try out.

Why use attendance monitoring system using face recognition?
Facial recognition attendance monitoring systems are a great tool for businesses of any size, this system can track employee performance, monitor who comes in and out of the office, and calculate payroll more efficiently than manual solutions.. With facial recognition software, there is no need to install people monitoring systems all day long. Automatic setup only requires setting the data information we need, the person information we need, and preparing the information we need to submit, reducing unnecessary hassle.. Facial biometric tracking allows you to identify strangers and track access to secure information. This is especially useful when you need to provide evidence that someone has entered your office. Automatic setup only requires setting the data information we need, the person information we need, and preparing the information we need to submit, reducing unnecessary hassle.. You never have to worry about forgetting passwords or recording your employees' working hours on paper. As a result, your employees will have more time to focus on pressing issues instead of monotonous and tedious processes.
The basic benefit of using facial recognition time and attendance management software is that it can increase your accuracy and productivity.. As more organizations begin to leverage machine learning and artificial intelligence solutions, we expect the market in this area to only grow in the near future.
Traditionally, companies have used thumb-based time and attendance systems, which can be a good alternative to card-based systems. They were not perfect and faced many setbacks in terms of reliability and security.  In recent years, attendance with facial recognition has gained attention. Companies with the technological capability and more standardized management processes have upgraded to facial recognition systems, but some small and medium-sized organizations are still using traditional time and attendance solutions.
Is it worth upgrading to a face-based attendance system? Let's take an objective look at biometric systems. 
Facial Recognition Time and Attendance Systems
Automatic attendance using face recognition is  system that automatically marks the attendance of current employees after recognizing their faces. In years past, attendance was done by roll call or by signing on attendance paper. Over time, the new way of keeping employee attendance records has shifted to using biometrics that require eyes, face or fingerprints as user input.
Among all the biometric technologies that are already in use on the market or already being researched, face recognition is an ongoing research topic in the field of computer vision, and its non-contact recognition technology has made a very significant contribution during the epidemic
What is face recognition?
Real-time face recognition attendance system is a method of identifying individuals by comparing their faces with faces stored in a database
What is a face recognition-based time and attendance system?
A face recognition-based attendance system is a system that automatically marks the current employee's attendance by recognizing the employee's face.
How does the face recognition attendance system work?
The system stores a database of faces. A screen, usually Truein's phone or tablet, is placed at the entrance and the employee simply walks towards it. Once the database match is triggered, the system will capture the attendance information in one second
Why do we need a facial recognition-based attendance system?
Traditional attendance methods are both time consuming and labor intensive. In large organizations that employ many employees, it can be difficult to take attendance manually and there can be misalignment of time sheets resulting in inaccurate and inefficient attendance. Employees can easily get rid of time recording options by stealing time in a manual based time and attendance system . 
Therefore, we need a face recognition-based time and attendance system that not only automates the time and attendance process, but also prevents employees from cutting corners.

What algorithm is used in face recognition time and attendance system?
Kuangsi algorithm
Where is face recognition used?
Every day, we check our phones thousands of times and eventually use facial recognition technology to unlock our phones. Facebook uses its own facial recognition algorithm to identify you and your friends. China has built an extensive surveillance system equipped with facial recognition technology to monitor its citizens. Facial recognition is a technology that is also used by the FBI to find criminal suspects
Facial recognition-based time and attendance systems are new
Being watched and/or spied on is a legitimate fear for many people. Many industries are still accepting the slow speed of facial recognition. However, the industry or area of work that would benefit most from facial recognition is time and attendance systems. Schools, offices, events, hospitals and even other places can use facial recognition based time and attendance system solutions.
Most of us can remember being in school attendance and having our instructors call out our names/registration numbers and we yelled "Now, ma'am!" . All of this could soon change with the introduction of facial recognition in these systems.

How facial recognition-based attendance systems work and how they work?
As you may already know, facial recognition systems require a database or pre-recorded data set to compare captured images and recognize faces.
A recent report from China states that a school installed facial recognition technology in its classrooms to monitor student behavior
Again, these cameras can be used to identify students and record their attendance in class. By submitting photos of various forms and documents to the school, students' faces can be added to the data set to record their attendance in each class.
Most offices and government buildings use biometric systems to record work hours and allow access only to those who are allowed to do so. While many countries have now implemented facial recognition for this purpose, they still rely heavily on fingerprint sensors due to the low potential for replication and fraud. The disadvantage of this is that recording fingerprints is a task that requires relatively more effort.
Advantages of face recognition based time and attendance systems
By far the most interesting implementation of face recognition in time and attendance systems is event attendance. The deployment of this system brings many benefits, especially for large events. Currently, most events such as large corporate conferences and concerts still rely heavily on tickets, passes and barcode scanning.
The inefficiencies of the current system start to become apparent when the audience reaches hundreds or even thousands of people. Checking tickets and scanning barcodes is a time-consuming process that depends on numerous variables.
Introducing facial recognition will reduce these inefficiencies, as most modern facial recognition systems can complete the task in less than two seconds. It's simply a matter of collecting images of attendees when issuing event passes.
It will also reduce the resale of tickets and the use of stolen or lost tickets by people who are not the official purchasers of said tickets.
Like most technologies, the system has its drawbacks ......
Disadvantages of facial recognition in time and attendance systems
Quality of the image
The quality of the reference image plays an important role in the recognition process. If the resolution of said image is not high enough, it may cause the camera to be deceived into thinking that the person being scanned is not the same as the person in the photo. A simple solution is to ensure that both the reference image and the scan are performed by similar cameras.

Depending on the quality of the input data, the system requires an appropriate amount of storage. This can be problematic if the data collected is of high quality and requires a large amount of storage space, especially for events with a large expected attendance.
Many non-advanced facial recognition systems cannot handle faces taken at an angle other than directly into the camera. The downside to this is that it makes the attendance scoring process slower and less efficient.
To cut to the chase, face recognition based time and attendance systems can benefit many industries. The time saved and the elimination of human error make the process more efficient. At Huifan Technology, we are constantly seeking to develop the best facial recognition technology for all types of industries. This is just the beginning of facial recognition and we believe we can achieve much more.
Frequently asked questions.
Why is multiple face detection based attendance system  better than thumb or fingerprint systems?
  • Almost 100% accuracy:
Thumb-based time and attendance systems often fail when fingerprints fade. Workers working in a fueling system cannot register their attendance with a faded thumbprint. Likewise, errors are returned by the application or by cuts on the finger. It's often frustrating to make multiple attempts at attendance before simply writing it down in a manual attendance register. 
This is not the case with facial recognition attendance. It has been tried, tested and proven to be virtually 100% accurate. Employees simply walk towards it and attendance is recorded. It works even if the hair changes or the employee gets older. 


  • Contactless security:
With covid-19, the world is increasingly aware of the risks of contact-based time and attendance systems. There is no time and attendance system, except a completely contact-free facial recognition time and attendance system. The user must simply show his face. The system is automatically triggered. 
Even after the world is free of the new crown virus, people will be aware of the contacts they make and it would be nice to provide a hygienic system. 
No complicated hardware: Thumb-based systems always require you to install a machine at the entrance. While the upfront cost is a barrier in itself, the machine also requires maintenance. When you choose a face time and attendance system like Huifan Technology, there are no complicated machines. You simply install the application on any Android or iOS system. Usually, companies only use tablets or cell phones for facial recognition attendance. 
  • Remote access:
Not every employee walks into the office every day. There are remote workers or on-the-go field workers who report directly to customer offices, distributor warehouses or other locations. If you have a rigid system that requires machines or hardware, it is not applicable to remote workers. 
With the FP08 mobile-based face recognition system, employees working away from home can take attendance from their own cell phones, no matter where they are. Companies can limit mobile-based attendance to specific geographic areas, geo-fencing them for greater security and control.

  • Amazing experience:
With attendance times reduced to one second and no action required on the user's end, facial recognition attendance is the best biometric system to date. It wows employees who don't need training and are happy to adopt it immediately. A facial recognition system is even more popular when it is based on a powerful application. Employees can track their records over the phone, and managers can track everyone in real time. 
  • Reliability:
A face recognition attendance system like Huifan Technology has an anti-spoofing mechanism. Employees may need to blink before attendance is recorded. It ensures that photos are not used to tag agents during the attendance process. 
Which biometric time and attendance system is more reliable and accurate?
Time and time again, it has been proven that fingerprint systems fail when fingers become dirty, greasy, wet or scuffed. Face time and attendance is almost 100% accurate.
Which biometric time and attendance system is more affordable?
Thumb-based systems require sensor-based machines to be installed at each site, which makes it very expensive to start and maintain. For face time and attendance, any Android or iOS-based phone may be sufficient. Even employees can use their own phones to track their facial recognition codes. Even retail stores with multiple locations or construction companies with multiple sites will find face attendance more affordable. 
Make informed decisions
There are many options available today. Not every fingerprint system or every facial attendance system is created equal. Evaluate the options between different vendors or brands and make an informed choice. Be sure to ask questions such as.
Does the time and attendance system have a geo-fence?
Does the system require hardware installation and maintenance? 
Does the system have mobile-based capabilities?
