If someone has to make his identifications clearly its okay, its not that when you give your identification you are already exposing yourself to danger, besides if you are not doing something wrong why would you be scared at all? In some point some measures are being given to users like identification for the verification of user, and aside from that if they would neglect it and then the user is doing bad things then it they would be the ones being blame and their company's at stake. Your identity is still safe.
