Its purpose is only health, and independent of the attendance control systems that teachers can carry out in their subjects.

All students, before entering the classroom or laboratory, should look near the door for the sign with a QR code. This will take you to the form that you must fill out (name, degree, building and classroom/laboratory, date and time of entry and exit).

If you leave the classroom/laboratory for more than an hour, you will have to fill out the form again. You don't have to do it between consecutive classes if you're going to continue in the same space.

It is explained in the following graphics.

Over the next few days, posters with the QR codes will be hung in all classrooms and laboratories.
