In Germany the system is shit too. There is a private monopol company that calculates and stores a score for you. The calculation method is secret, but we know several things can lower your score, such a having too much bank accounts/credit cards, moving too often, if you ever had debts and how fast you paid them and so on. When you ask a bank for a loan, they check this score and may decline if it’s too low. There are some people who have problems getting a loan because they have no records for their score.
