What's the risk? Well, even if the odds of getting caught are low, fines and deportation at best, prison at worst.
- A girlfriend in the US, who want to see his boyfriend in the EU - after one year.
- A Gastarbeiter from Ukraine, who needs to work and earn money (and thus needs to travel to Poland).
- A Swedish rich guy who needs to get out into the sun in Thailand.
I can continue the list.
It's a question of risk versus reward. What is the incentive for the average leisure traveler to use a fake travel document?
Well, technically it's not a fake document. It's real. It's not like a fake passport. It's just that the underlying data in that digital passport are wrong.
I can't imagine many people are dumb enough to take that risk/reward proposition.
You can already buy negative PCR test results in the middle of the day/in the middle of a busy street in Russia, Ukraine, Kenya and South Africa.
If there are so many sellers, there must be buyers.
