The process of in-class control and monitoring of students' examination activities is traditionally conducted manually, without the support of technology. The workflow can include tasks for attendance record or dishonesty control. The tasks include identifying the students before, during and after the beginning of the evaluation activity. Can also include examination room allocation to the activity, as well as the distribution of students per available examination rooms and distribution of students inside the room according to a classroom seating plan (which can have a varied setup). However, with a large number of students, the execution of these tasks becomes challenging to perform efficiently, requiring innovative techniques or tools to support them effectively. In this work, we propose the design and implementation of a mobile system based on IoT technology and MIFARE student's cards to support the lecturer efficiently during the examination workflow. We propose the use of current indoor location technology, and we build a proof of concept prototype, validating it in a real educational environment.
