They can be copied, or are copies. If you have a copy, the idea to manipulate it's content is not far, for example the name.
People are actually selling such simple copies.
Yes, the data in the barcode contains encryption and signatures, so it is not easy to manipulate that, and when it is scanned, there are many checks running.
This is untrue.
The idea to manipulate the name is not feasable. And if it were it would not be used to fake Deutschlandtickets, but rather anything else that needs cryptography and brings extremely more money.
People are either selling tickets that are not scannable, scan on the wrong name, or in one case, got access to the private key of a regional provider and had the possibility to legally sign tickets. These tickets were then undistinguishable from legal ones, because they were legal ones (for the purposes of the system). But these tickets would also have been valid if they were not screenshots.
Yes. The fraudsters can change the visible name, not the one stored in the barcode. I have seen some that looked like really childish "paintbrush" copy & paste.
The point is: these things are not made to stand a check of the barcode. They are just made for selling them to stupid people.
And that scheme has worked in the very beginning of the Deutschlandticket. It does not work anymore now, because nobody accepts a screenshot or PDF anymore.
Give me 20 minutes in an HTML editor or android studio and I can make you an "app" that looks real, but isn't. You don't even need to be a "real" programmer for that. It looking real proves literally nothing
