Myplace offers an Attendance module. This is a 3rd party plugin that allows staff to define sessions that students are expected to attend.Attendance can either be taken by the staff leading the session or students may be allowed to self-register their attendance, via the Myplace activity or via a QR code that is provided to them during the session.
Further details on how to use this plugin can be found at https://docs.moodle.org/310/en/Attendance_activity
