In order to stay at an SCR-connected campsite you need to register. When you do, you get a Camping-ID, which is an identification document used to check in and out at campsites connected to SCR. The Camping-ID is free of charge and you can access it in the app My Camping Key. In the app you have full overview and control over what information we have saved about you. You also have access to a log book where you can see which campsites you have stayed at.
If you have a plastic Camping Key Europe-card that does not register in the app, it is still valid to use in Sweden, just not in the app. A Camping-ID is however necessary as a complement to a non-digital CKE to check-in at SCR-connected campsites in Sweden.
