Have to say i was always surprised in the past when friends or colleagues printed their passports to get access to normal discussion boards...not even talking financial stuff. You never know what those other people are going to do with your data and till the whole thing is solved, you usually have a looooooad of trouble. In some cases, data is used for years and it could become even more expensive for you to prove all the time who you are and - more important - what you have NOT done.
