### One-sentence description Make payments linkable to registration ### Why? When checking payments, you can only see a 'payment' object but apart from that they have no real use. However sometimes it really is useful to check all payments done on a certain day. ### Current implementation The current implementation of payments shows payment objects. However when in a payment object, you can't easily go back to the registration that is connected to the Payment object. ### Suggested implementation Being able to see the registration that the payment was connected to.
