Berliner Sparkasse can collaborate with schools and appoint one or two persons per school to open up accounts of kids in school..
Save their pocket money and deposit it easily in the school itself with this they will learn savings and they will also get connected to berliner sparkasse so that when they grow up they will continue with the same bank.
They should have easy access to the accounts which means with less formality and paper work so that students will feel easy to access it.
The interest rates of these accounts should be a little on higher side to create interest among them
There should a limit to total amount a student can deposit so that their parents dont start misusing the higher interest rates.
These banks inside school may also provide loans to those who are incapable of paying the fees at once with less rates these can be termed as study loans.
The bank may also vary the interest rates according the income of parents of the students the poor kid can enjoy higher rates..
The bank may not need to appoint employees for this they may talk to some teachers for it and give them some extra money for doing this.
THIS SCHOOL BANK CAN ALSO ASK FOR DONATIONS AS IT IS FOR A SOCIAL CAUSE(PROVIDING STUDY LOANS AND ALSO HIGH INTEREST RATES FOR POORS)
