In today's Guardian, https://www.theguardian.com/money/2...d-with-court-for-using-screenshot-of-e-ticket, is a report of a passenger attempting to use a screenshot of an "e-ticket" with a perfectly readable bar code, but being effectively compelled to pay £161.30 to avoid a threatened prosecution. The thread title includes the view of Transport Focus of the case, and the payment has now been refunded. This is the sort of thing which makes me a reluctant user of "e tickets" (I used a Virgin one last week) and I absolutely will not use "m tickets" which require use of some sort of "app". I've worked with computers since 1984 so perhaps it's my familiarity with the failings of technology which make me feel this way. However there was no failure of technology in this case, there may have been a failure in staff training which resulted in what seems to me a totally unacceptable chain of events, only slightly mitigated with the refund conclusion. Nonetheless these sorts of tickets are clearly the way of the future, and rail companies need to do better than they did do in this report, and show that they are doing so.
