Introduction
In today's world, where speed and accuracy play a prominent role in all aspects of life, managing the entry and exit of employees in organizations and companies has become particularly important. In this regard, time and attendance devices, which are responsible for accurately recording working hours and the presence and absence of individuals, have become one of the essential and vital tools for every business. In the past, these devices mainly relied on traditional methods such as fingerprints, magnetic cards or passwords. However, with the advancement of technology and the emergence of artificial intelligence (AI), there have been tremendous developments in this field that have increased the accuracy, speed and security of time and attendance processes.
Traditional time and attendance systems and their challenges
Before the advent of AI time and attendance devices, many companies used traditional systems to control the entry and exit of employees. These systems typically relied on one of the following methods:
1. Magnetic cards and RFID: Employees had to swipe their cards when they entered and exited. Although these systems were simple, they were easy to cheat and abuse.
2. Fingerprints: With advances in biometrics, fingerprint systems were designed to identify individuals. This method was relatively accurate, but there was a possibility of mistakes or delays in identification, especially in workplaces with a large number of people.
3. Passwords and ID cards: Some organizations used ID card and password systems to control entry and exit. However, this method was also easy to forget, make mistakes, or be stolen.
Although these systems were useful at the time, they had many problems such as lack of accuracy, slow speed, and the possibility of fraud. Also, manual processes and the need for physical presence to record attendance also caused problems on a larger scale.
The Entry of Artificial Intelligence into the World of Time and Attendance
With significant advances in various fields of technology, especially in the field of artificial intelligence, new time and attendance devices have come to the market that are built on these advanced technologies. Time and attendance devices based on artificial intelligence have been able to solve the problems of old systems and operate with greater accuracy and speed.

These systems use various technologies such as facial recognition, motion behavior recognition, and voice recognition to accurately record entry and exit. Here, we will examine these technologies and their benefits:
1. Face Recognition
One of the most important and well-known technologies used in AI time and attendance devices is face recognition. These systems use high-quality cameras and artificial intelligence algorithms to identify a person’s face and compare it with data recorded in a database.
The advantages of using facial recognition in time and attendance devices include:
• Very high accuracy: Facial recognition systems, using complex algorithms, are able to recognize faces in different lighting conditions and even in the event of minor changes in the appearance of people (such as wearing glasses or changing hairstyles).
• No need for physical contact: This feature is especially important in pandemic situations such as COVID-19, as there is no need to touch the device or ID card.
• High speed: The facial recognition process is completed in less than a few seconds, which allows people to enter and exit quickly.
2. Motion Detection
AI systems can also use motion detection technology to identify people. These systems are able to identify a person's body movements and track their presence in different places by examining specific behaviors. This method is especially suitable for environments where people are frequently on the move.
Advantages of Motion Detection:
• Accuracy in crowded environments: These systems can accurately detect human behaviors even when there are a large number of people in an environment.
• Fast and efficient: Motion detection systems do not require physical interaction and automatically use the movement of people's bodies to register presence or absence.
3. Voice Recognition
Voice recognition is another new method that is specifically used in some artificial intelligence-based attendance systems. In these systems, instead of entering a code or using a card, a person only needs to give a specific voice command that is recognized and processed by the system.
Advantages of voice recognition:
• Easy to use: People can easily log in to the system using their voice.
• High security: These systems can analyze the voice and ensure the identity of the person, which increases the security of the device.
General Benefits of AI Time and Attendance Devices
AI time and attendance devices have many benefits due to the use of complex algorithms and machine learning, including:
• Very high accuracy: These systems have the ability to identify people more accurately and make fewer errors than traditional systems.
• Increased speed: The attendance registration process is faster and more efficient.
• High security: Due to the use of biometric identification technologies and complex data analysis, the possibility of fraud and manipulation of information is minimized.
• Reduced costs: The need for manual and time-consuming systems to check and reconcile attendance is reduced.
• Reduced health risks: Due to the lack of physical contact, the risk of disease transmission is reduced.
Conclusion
Ultimately, AI time and attendance devices not only increase the accuracy and speed of entry and exit processes, but also provide a system that
