On most cards it states which type of card it is, for example Commuter Pass, School Pass, Rejsekort Corporate. However, on Rejsekort Personal, Flex and Anonymous it does not state which type of card it is. You will always be able to recogniseRejsekort Personal and Rejsekort with Commuter Kombi by the fact that your name is stated on it and there may also be a picture of you. However, Rejsekort Flex and Anonymous may look the same.
You can check by placing the card in a Rejsekort machine or by going to Self-service, where you will find an overview of your card(s) with information about Rejsekort number and card type.
If you do not have a login for Self-service or cannot see your card in the overview in Self-service, it is most likely because you have a Rejsekort Anonymous. If you want to be completely sure, you can check the back of your Rejsekort: If you see a map of Denmark, it is a Rejsekort Anonymous.
