I have booked an advance ticket for the Stansted Express. I opted to have the ticket sent by email (e-ticket) rather than by SMS to my phone (m-ticket).
The info on the Stansted Express site says that I need to print the ticket before I travel.
Do I really need to print it out, or can I just show the ticket (it's a PDF which contains barcodes for scanning) on my phone?
As you state, the FAQ answers your question:
This ticket needs to be printed at home and presented to the Stansted Express station or onboard staff to be scanned as a valid ticket for travel.
In other words, if you present your phone with the ticket on, the inspector may tell you that your ticket is not valid, and you will have to pay for a full price fare on the train. I have heard of this actually occurring.
It is, of course, a non-sensical policy, but unless you comply, you are risking a fine.
No need to print it, since you can retroactively import the ticket into the Stansted Express mobile app.
You only need the ticket reference number and the email address you used when purchasing the ticket. Install the app, login or create an account, select Account > Import Ticket, enter the information and you are done.
