The image is added for creating and ordering a student card (digital and plastic). When the picture is added during the registration phase, you can use your digital student card at the same time. The same image is also printed on a possible plastic card, so adding an image when registering speeds up the ordering of a plastic card later. However, you don't have to add the picture right away, you can add it later if you want. If you don't want to use a digital student card or order a plastic student card, the picture is not mandatory. In this case, you can use Frank's benefits online.
