Will accept an electronic boarding pass for a report on working with 2019?Why?

I recently went on a business trip the truth is on the train and the ticket is ordered via the Internet and in the accounting Department still demanded from me a paper , told to report anyway, or they themselves are too lazy to look it up online and specify the registration link or are they still working in the old way, but was forced to bring the printout , here we have bureaucracy that we receive when innovations around the world will report on biometric data.
