Monitoring student attendance during class hours required by each university due to the presence of the students proved to have a positive correlation with the performance of students during their studies. Most universities still use conventional techniques to record student attendance during teaching and learning in the classroom. Conventional techniques are inefficient and ineffective because they tend to spend a lot of time to record attendance and fraud appeared in the form of false presence. In this study a system that combines smart card and fingerprint technology is proposed to reduce fraud during the process of recording attendance in class, as well as making it easier for academics to manage attendance data. This system consists of card personalization applications, card reading applications, and attendance monitoring applications. The test results show that all three applications in this system give the expected results. In addition, the system is proven to be able to reduce frauds that occur in the classroom because there are two validation processes at the time of recording attendance namely smart card and fingerprint validation. With fingerprint validation, students cannot commit fraud because fingerprints are difficult to be manipulated or duplicated.

As a currently popular technology, the use of smart cards continues to increase in various fields and the rapid development of technology. Therefore, data security stored on a smart card needs to focus on avoiding misuse of data by unauthorized parties. However, it is not enough for the security mechanism to be carried out only during the communication process of sending data. Then, the mechanism for securing data on the smart card also needs to be done. In this study, a data security technique using dynamic keys is proposed by changing the key and access conditions on the smart card according to predetermined rules. Dynamic keys are a new mechanism proposed to authenticate smart cards using a different key on each card. This technique ensures that the keys used to access each smart card are different so that the risk of data duplication and modification threats can be minimized. In addition, this mechanism is a low-cost security privacy protection. The test results show that the data security technique using dynamic keys ensures that read and write access to the smart card can only be done if the keys match the rules.
