Discription
~~~~~~~~~~~
Geldschein-Pruef is a tool for checking the numbers of the german
moneysheets :-). It is just a simple usage in Ansi-C of the Dieder-
ischen Groups of the calculus of the 8-Checkcharacters-algorithm.
Still no problems has been sighted.
Background
~~~~~~~~~~
Just as I read a book about coding-theorems from the university-library
I saw the diederischen Groups and the 8-Checkcharacters-Algorithm. When
this articel in addition was about money, it had my attention. I read
the articel about matrix and the mathematic aspect of it and learned
some hints about matrix-calculation.
But not the usage of the "checked" numbers of the german bank were
interesting, as well the power of the error-correction of the dieder-
ischen groups. This comes here not at all to the light but on the
further pages of the book this will be focused.
Requirements
~~~~~~~~~~~~
- Any OS with an Ansi-C Compiler
- a lot of money to check their numbers :-)
