Here is a poll for people who have actually used e-tickets. What are e-tickets? basically PDFs that contain an Aztec barcode which can be shown on any device, or you can print them. What are NOT e-tickets? the old Print@Home tickets, which required a form of ID, m-tickets, which require activation or anything else that doesn't meet the e-ticket standard. For those of you who have actually used e-tickets, I'd like to know what you think of them? At first I was sceptical but my view now is that they are great. I usually have two devices on me so I can store it on both devices. If I am making a long journey and am concerned I may run out of power, I can print them, though I don't usually bother to do this. The only 'problems' I have had is that some barriers have not had the keys to decrypt the e-ticket, resulting in having to be let through the gates manually. However my experience with this has been no worse than with paper tickets, to be honest! I like being able to wait until the last second before buying a ticket in some cases and I like not having to visit a ticket machine. For example I could be on a train already and decide to extend my journey, and buy the ticket and remain on board without having to get off and end up on the next one.
