I am a host in Booking.com. Sometimes, customers do not want to show their id or to take their social security number. In that case, I am in risk to give shelter a criminal. So can I refuse those customers who does not want to give id photoor id number? Please inform me. Also how I can set up id requirement from each customer in Booking.com? And it can be good If booking.com can accept some partial demage deposit from the customer. For example, collecting 50% damage deposit by booking. Com and another 50% by host from the customer. Then this way, we can really avoid criminals. Thanks.
