As more organizations are switching to remote work and cloud-based processes, data security and authentication have become their primary focus. This has boosted the demand for biometric security systems that can be deployed for various purposes including attendance tracking and employee verification. Today, manual attendance tracking is no more feasible owing to its limited scalability and labor-intensive process.

A biometric attendance system—based on the face recognition technology—can help in setting up an automated employee attendance tracking system for any business. With many biometric products to choose from, how do you determine which system is best for your organization? To make it easy for you, here are seven essential features that your biometric face attendance system must-have:

1. Real-time face detection and processing

To be effective, a biometric face attendance system must be able to detect and identify faces from any live video feed. This includes detecting a face from an awkward angle or even in low-light conditions. Besides fast face detection, your biometric system must be able to quickly process and identify the detected face from the thousands of employee database records. On average, face recognition tools take less than a second in detecting and matching any face image. AI-based face recognition tools are effective in detecting multiple faces in a single field of camera view and match them against existing face images stored in databases. Going by the CSIS statistics revealed in April 2020, AI-based facial recognition algorithms have an error percentage of just 0.08% or less than 1 error for every 1,000 images.

2. Detection of a live person

In short, your biometric face attendance system must be able to differentiate between a real person and a facial photograph. This feature is critical in preventing any kind of security breach or unauthorized persons illegally accessing your backend systems. An example of live face detection is the use of 2D or 3D image sensors that can capture all contours of a face before applying the algorithm to match them to the stored image in the database.

3. Offline attendance tracking

Most face attendance systems require continuous internet connectivity to record and store both clock-in and clock-out time of each employee to the organization's HR or attendance systems. Internet connectivity is of particular importance in tracking work-from-home employees. So, what happens to attendance tracking when internet goes down? Your biometric attendance tool must be able to function in the offline mode and store employee work-related data. This data can be then synced to the database system once the internet connection is restored.

4. Seamless integration to HR and payroll systems

By accurately tracking employee attendance, face biometric systems can be beneficial in improving overall work productivity and reducing administrative costs for your HR team. For this, ensure that your employee attendance system can be seamlessly integrated with your HR and payroll systems. By doing it, you can keep track of:

  • The current work schedule of each employee
  • Number of daily or monthly hours worked by an employee
  • On-leave employees
  • Monthly or weekly hours worked by each employee and generate reports for the same
5. Effective access control

In addition to accurate time tracking, biometric attendance systems must also have integrated access control to ensure that only genuine and authorized users can enter the system. Among all biometric technologies, face recognition is also a “contactless” mode of user authentication. This allows safe access to employees without performing any action or carrying any identification cards.

Additionally, biometric attendance systems can provide access control on the basis of the following three categories:

  • User or access only to users from a selected project or department
  • Time or user access during a selected time duration
  • Zone or users working in a selected geographical zone or location
6. Ease of use

Your face recognition tool may be packed with multiple features and add-ons, but is it user-friendly? For instance, your attendance tool can have a centralized dashboard to display the attendance-related data of all your employees. Additionally, it has the provision to add more new employees, each with many face image captures taken at various angles. Other user-friendly features can include easy installation, user registration and report generation.

7. Support for multiple platforms

Remote-working employees can use their own devices such as laptops, tablets and smartphones for attendance tracking. This makes it necessary that your biometric attendance system or mobile app must support multiple platforms including Android and Apple iOS. Additionally, it should also be able to support operating systems such as Windows, Linux and macOS to make it compatible for most of the employees based all around the globe.
