Rejsekortet is a travel card popular with commuters and frequent travellers in Denmark, but also offers a card to foreign visitors; Rejsekort Anonymous which does not require an address in Denmark or any personal details. You can buy Rejsekort Anonymous at Copenhagen Central Station's ticket office and several other places. The Rejsekort Anonymous card itself costs DKK 80, and when you buy it at a ticket office or one of the Rejsekort machines, you are expected to add DKK 70 to the balance to cover the cost of travel.
