"Your ticket or ID please".
Time is short and the next train will arrive in 3 minutes. You run through the city like someone who wants to win the marathon. The train stops, you reach the stop and get on breathlessly. Phew, lucky again. The next opportunity in this direction would have been an hour later. But you have made it. In a hurry, you sit down in the seat next to the good-looking lady in the flower dress. Perfect. Apart from the small sprint just now, you reach your next appointment at the scheduled time and in pleasant company. Now nothing can go wrong.
As the ticket inspector makes the rounds, you remember that you forgot to buy a ticket in your hurry. When it is your turn, you are embarrassed and ask the ticket inspector for leniency. But unfortunately, he is not in the mood today and seems visibly annoyed. He wants to see your ID and slap you with a hefty fine for fare evasion. Embarrassing, because the lady next door and everyone else will hear the conversation between you and the ticket inspector.
Is he allowed to ask for the ID card at all and sift through personal data?
From a purely legal point of view, he is not allowed to demand your identification papers. Only the police are authorized to check your identification documents. You can therefore refuse to allow the inspector to inspect them. But he can still call the police, who in turn have the right to check your ID card.
If the inspector asks you for your address or name in advance, you should only give him the most necessary information. Even to the police, you do not have to provide detailed information about the situation. Because sometimes less is more. And if you remain silent, you do not admit your guilt.
And what happens after the data check?
Unfortunately, the transport company is allowed to use its domiciliary rights. This means that you have to leave the lane.
