My parents took the 5am cork-dublin bus today. (the 15th of August) They took a screenshot of the QR code sent by another member of our family to travel, as a gift trip to Ireland. They do not speak english at all, and handed their phone with the QR code to the bus driver, who did not even bother checking if they are on the list of passengers or not (for example by asking their IDs or passport), when the same driver could not find some 8 digits numbers with the ticket to identify them. The bus driver did not allow them on board, as my guess is that he does not have a QR code reader!!!! What's the point of printing tickets with QR code, then. I tried to reach out to the person who booked the ticket, but at 4:45am, who would wake up if you are living on the other side of the world? Finally, when I begged the driver that we were willing to pay for the tickets again, he finally looked at the passenger list, and allowed them on board. So either he did not have a QR code reader which is fine but then he should have a passenger list in the first place to avoid this type of arguing and stress.
