The present invention is directed towards an electronic ticket suitable for providing entry to an event. The electronic ticket is capable of being stored, in electronic format, on a mobile user device. The electronic ticket comprises a dynamic entry code for the event such that the dynamic entry code is transitionable from an inoperable state to a functional state, whereby entry to the event is only possible when the dynamic entry code has been transitioned to the functional state. The dynamic entry code is a visual code which is non-readable by humans and is stored in a memory of the mobile user device, such that the inoperable state of the dynamic entry code prohibits the visual code from being displayed by the mobile user device and the functional state of the dynamic entry code permits the visual code to be displayed by the mobile user. The advantage of providing the dynamic entry code is that the electronic ticket can hide the entry code until close to the event start time so that a ticket tout will find it difficult to sell the ticket on as a purchaser would have less confidence in buying a ticket which does not display the entry code required for admission. Moreover, a ticket fraudster cannot duplicate the ticket.
