Yet if there is nothing to hide, why it would be? Couple years ago in UE (especially eastern countries), companies, especially para-banks let people borrow money just by creating account and submitting ID photos. There were tons of scammers that had used stolen IDs just to get money and withdraw (with the help of poles, i.e. people who did not know that they were doing something wrong) in cash. After years of court cases, UE implemented a law that prevents such issue to happen again, (and if do), companies are obligated to pay enormous retribution for even ALLOWING that to happen. So at this point, as I'm member of country that is a member of UE, I do not see anything that could go wrong way by providing ID.
