Attendance face (Face ID Attendance) is the method to record the working time of the staff using technology face recognition automatically. The system uses a camera integrated artificial intelligence (AI) to scan, analyze, and collate facial features of each person with the subscribed data available, from which verify the identity and recorded the time in – out quickly, accurately, no need to touch or swipe the card.
In the era of transformation, when asked about the effect transparent, accurate in personnel management is increasingly high, the method of timekeeping tradition as swipe cards, fingerprint or window gradually revealed many limitations. The appearance of the dot, fair face, Face ID has opened a new direction for the business to help automate the process of recording the time work, at the same time prevent attendance pussy, skewed data, and optimal personnel costs.
The article below Lac Viet Computing will provide a comprehensive view of the attendance system using face recognition from the principle of operation to the specific benefits when the application is in admin attendance – payroll business.
1. Attendance face is what?
1.1 the Concept and mechanism of action
Attendance face (aka attendance face recognition time attendance, Face ID) is the method to record the working time of the employees based on the technology of face recognition by artificial intelligence (AI). Instead of having to swipe the card, press fingerprint or enter a PIN code, employees just standing before the device has camera recognition, the system will automatically match the face with the saved data, verify identity and noted-time out – on accurate to the second.
About the mechanism of action, time and attendance system face using the algorithm, deep learning (deep learning) to analyze the characteristic face of each employee as the distance between the eyes, shape of the chin, the curve of the lips... The characteristics which are encoded into “an identification string” single machine can help get the right people even when they change hairstyles, glasses, or wear a mask.
For example: employees entering the office, the camera identification in less than 0.5 seconds, time data, timesheets will be automatically sent about the system of personnel management – no need to manipulate or signature confirmation.
1.2 The difference between clocking the face and traditional methods
Compared with the traditional formula, such as magnetic card, fingerprint or PIN code, attendance system, facial expression outstanding advantages in three aspects: accuracy, security, automation capabilities.
| Criteria | Recording/fingerprint | Attendance face |
| Accuracy | Depends on the manipulation user to false when forget swiped card or sensor error. | Accuracy up to 99.9%, automatically recorded without contact. |
| Security | Fraud “dot black” by card or fingerprint author. | Authentication, single face, almost impossible to fake. |
| Automation | Data often must enter into timekeeping system or Excel file. | Attendance data automatic synchronization of system HRM or payroll software. |
Special technology of face recognition can accurately recognize even in low-light conditions or when workers wear a mask – feature is developed strong after translation stages COVID-19.
2. Principle of operation of the timekeeper recognize the face
In the attendance system face today, the whole process takes place in seconds, but includes many steps sophisticated processing to ensure the speed – accuracy – security. Here are 4 main stages in a process attendance by face recognition is widely used in the modern enterprise.
2.1. Face detection
In the first step, the integrated camera AI technology in the timekeeping device will perform the task, face detection, users in the range observed.
To achieve high accuracy, employees need to stand straight, facing directly on the screen and keep suitable distance (usually from 0.5 to 1 meter). The system will identify the basic characteristics such as face shape, eye position, nose, mouth.
The highlight of this technology is capable of stable operation in low light conditions or angle of inclination to help businesses maintain accurate timekeeping even in the environment there are many factors that interference such as factory, workshop production.
2.2. Face analysis
After detection, the system conducts analysis of facial features, on the basis of 2D (or 3D depending on the equipment). Elements of the biometric as the distance between the two eyes, the curve of the eyebrows, shape cheekbones, the length of the nose... is recorded and converted into data points.
Each face has thousands of characteristic different help system built “map face” (face map) separately for each individual.
Analyzing this eliminates the factors causing deviations like changing hairstyles, glasses, or mask – issues that many businesses fear when applied timekeeping with face ID.
2.3. Convert image to data
Whole data, characteristic face is transformed into mathematical formula by AI algorithms, to create a coding sequence single called “face print” or “face ID”.
This code does not save the original image, which is only hosted identifiable information is encrypted to help ensure the safety of personal data, comply with regulations, security biometric information according to standard ISO/IEC 19794-5.
The encryption helps businesses peace of mind when deploying attendance system face in many places, at the same time avoid the risk of being copied or tampered data.
2.4. Search for comparison of data
The last step, the system will compare the number of faces just scan with the database has stored to identify the employee.
If a match manipulation attendance is recorded success along with time, location and device used.
AI technology now allows treatment process for comparison, this is just in 0.3–0.5 seconds, even when the data consists of thousands of employee records. This helps businesses minimize congestion when attendance peak hours, especially useful for factory or the industrial park, east of labor.
Thanks to this process, businesses can:
- Tự động hóa hoàn toàn process timesheets, loại bỏ việc điểm danh thủ công hoặc quẹt thẻ.
- Prevent fraud timekeeping pussy, increase transparency in the management of working time.
- Shorten processing time data in payroll, thanks to the system links directly with payroll software.
- Increase experience staff, when just step through the camera is complete attendance – fast, convenient, non-contact.
3. Guide and note when using the attendance system face
The attendance by face recognition only achieve maximum efficiency when users make correct posture, distance, expressive recommended. This is the key factor that helps enhance the accurate identification and shorten the duration of recorded attendance, especially in an enterprise environment there are number of personnel.
3.1. Position and distance when attendance
Timekeeper or camera recognition are typically installed at a height of about 1.5 meters from the ground, equivalent to the vision of the average adult.
- The optimal distance to get the exact opposite is from 1.5 to 1.7 meters.
- Just in case, flexible (for example, people high or lower than the average), employees can stand in the range of 0.3 – 2.5 meters for the system to easily scan the face.
- Distance is too far or too close, everyone has a camera false identity, especially in low-light environment or have many people on the move.
Practical suggestions: Businesses should mount visual instructions (like barcode marked deck) to help employees easily locate appropriate stand, reduce the error operation when timekeeping.
3.2. Standing posture, facial expression
- Keep facial expressions naturally, avoid the expressive, the excessive, such as laughing, frowning, or bowed.
- Orientation straight head, eyes looking directly into the camera for several seconds for the system to recognize stable.
- Do not turn your head, tilt your face or talk while attendance.
- If wearing a mask (with machines that support AI recognize the half face), should keep the mask fixed to ensure the matched data.
3.3. Note when registering original face
The registration process faces step is the foundation for the system to accurately recognize in the dots later. Therefore, employees should strictly comply with the following requirements:
- Keep your distance from 40cm – 80cm between the machine and the face in at registration.
- 't change facial expressions throughout the process (don't laugh, don't blink, don't cover the face).
- Not a hat, wearing sunglasses or a mask (except high-end devices that support recognition when wearing a mask).
- If regular glasses should register two versions face with glass and without glass to increase the accuracy.
- When registering, only made one by one, to avoid two faces appear in the frame.
4. Any business suit attendance system face?
4.1. Enterprise-scale hr or more branches
Enterprises with number of employees or operations in many different branches, managing time, attendance and monitoring the presence of staff is a challenge. The form of timekeeping tradition as magnetic card or fingerprint to errors, fraud, or spending a lot of effort synthetic data.
Attendance system using face addressed to the this problem by synchronizing real-time data, system center, allowing managers to monitor the situation attendance of the entire branch on a single platform. For example, a retail chain has 20 stores in many provinces in just a few clicks of the mouse is able to understand the rate of on-time of the entire system.
Values bring:
- Reduce 90% of the volume of administrative work related to the general public.

4.2. Business applicable model flexible working
After the pandemic, many businesses turn to the model the flexibility to work (hybrid) – combination of work in the office and remotely. This poses new requirements in the timekeeping: how to manage hours of employees that still ensure transparency, non-infringement of privacy.
Timekeeping solution face built-in GPS is the answer. Staff can stop the remote through the mobile application, the system will verify the face and geographical location, ensure that person actually present at the place of work. With businesses that have sales staff, technicians or personnel often on the move, this feature helps to manage tight time without direct supervision.
For example, A logistics company with hundreds of the driver can monitor the working status of each person, through attendance data location instead of relying on reports manually.
According to a survey by PwC Vietnam (2024), more than 64% of business applicable model flexible work said they are looking for or have deployed attendance system using face have integrated GPS to ensure optimal employee performance.
Values bring:
- Easy timesheets anytime, anywhere.
- Minimize fraud in the model of flexible working.

Trong chấm công, độ chính xác là yếu tố cốt lõi quyết định tính minh bạch, sự tin tưởng giữa doanh nghiệp và nhân viên. Một phần mềm quản lý máy chấm công bằng nhận diện khuôn mặt hiệu quả cần đạt tỷ lệ nhận diện chính xác từ 99% trở lên, đồng thời có khả năng phân biệt khuôn mặt thật với hình ảnh, video hoặc mặt nạ giả.
The advanced solution currently using AI technology, Deep Learning to learn and remember facial features over time, thanks to that still accurately recognize whether staff appearance change slightly (as for beard, glasses or wear a mask).
About data security, businesses need to ensure the system complies with the safety standard international information such as ISO 27001 or GDPR (for data storage in the cloud). Face data, which is a form of biometric information sensitivity should be coded in high level, avoid leak or unauthorized access.
Enterprise value received: ensure avoid fraud attendance, at the same time strengthen the confidence of staff to the transparency of the organization.
5.2. Processing speed, the ability to operate offline
One of the factors often overlooked when choosing software clocking by Face ID is processing speed and stability when network connection trouble.
The advanced system can now recognize faces within 0.3 – 0.5 seconds, to help timekeeping process takes place smoothly even when there are hundreds of staff out at the same time, avoid congestion before timekeeper.
Besides, the ability to operate offline feature is necessary, especially for factory, industrial area or place of work has the infrastructure, the network is not stable. When the network is interrupted, attendance data still be temporarily stored on the device, automatically synchronized when the connection is restored.
