I’ve bought Oasis tickets from Stubhub after failing to get them through any other means. I initially got a pdf file with a screenshot of the tickets to print out but after a call to Stubhub to say that’s obviously unacceptable, I’ve now been sent an email attachment with tickets with a ‘live’ qr code (the one with the continuous purple line going round the code). I’m still a bit suspicious after the first ticket attempt but wondered how easy it would be to fake a dynamic qr code? Stubhub are assuring me that these tickets will be valid.
