A method and system for recording the presence and absence of pupils and students by means of a data logger. With the data logger, which is provided with a clock, the identity of a contactless radio-frequency identification label is read to record the presence of the relevant pupil and to transfer this at a later time to an information processing system. To simplify the log-in operation, a wall data logger where the pupils themselves log in, can be arranged at the entrance to the classroom, so that all information can be read in one operation into the hand data logger of the teacher. The hand data logger can further be provided with a microphone and a digitizing circuit for storing a small amount of spoken text and transferring it to the information processing system. If the transfer has proceeded well, the stored information can be removed from the data logger. |
