Easyjet - a ticketless airline?

Question

Hi. I have booked my easyjet flight online and was surprised to find that they don't issue their customers with tickets...so what other documents do I need to bring with me when boarding the flight?!.....I have a booking reference bar code which can be used as they put it for a "faster boarding" which was printed off from the booking online....is this all I need to bring along with my passport?
