Renting a car or booking a hotel? It might be very easy to have the staff member at the desk make a copy of your identity card, but the vast majority of service providers do not have legal permission to do so!
This is not without reason, because your passport is a serious collection of very vulnerable personal data. In particular, the citizen service number (BSN) and your passport photo and signature are vulnerable to identity fraud. Therefore, never just give out a copy.
Although it is quite conceivable that your reticence will result in a discussion with the hotel staff or the landlord, you will often get quite a long way if you calmly and clearly explain why you do not want to have your ID document scanned or copied just like that. That way, your information remains protected.
