Each single payment must amount to at least 50 kreutzers or a multiple
of 50 kreutzers.
The balance in favour of a depositor can at no time amount to more than
1,000 florins including deposits paid in and interest added to the
capital.
Deposits of 50 kreutzers can be made in postage stamps, or in special
postal savings stamps as soon as such stamps are issued by the Minister
of Commerce. These stamps are to be fastened on forms supplied
gratuitously.
