2. Motivation
In most universities, teachers take attendance by calling
out the names and surnames of students, and then
marking them, while, in others, teachers pass around a
sheet of paper, asking students to sign in attendance sheet
just next to their surnames. Both practices have their
drawbacks. In the first case, if numerous groups attend the
lesson, checking all of these students by name and
surname might take about 10 minutes out of each lesson;
in the second case, friends of absent students may write
down their names and surnames. These practices place
university teachers and their institutions at considerable
disadvantages when it comes to taking attendance.
To rectify these systematic failings, we have
decided to put the RFID-card into service. Each card has a
unique ID, precluding the duplication of a card.
