If you own a Museumkaart or BankGiro Loterij VIP-kaart, a ticket is not needed. Scan your card at the register. If you purchase a discounted ticket (CJP or student), you'll need to show an original, valid card with your e-ticket.
Tickets are valid until a year after purchase. A ticket grants access to the Sound and Vision experience and the temporary exhibition News or Nonsense.
