The product I am to improve is the coin roll dispenser (CRD). This kind of machine delivers automatically coin rolls to the customer when he introduces either notes or a bank card. The aim is to introduce a new functionality call “automatic balance”. The machine must be able to know the amount of coin rolls it has inside at any moment and without receiving any external information.

For this purpose a prototype must be designed, assembled and tested. Therefore the project will combine sensing technologies, electronic processing, and hardware and software development.

The results must proof that the system is completely reliable.
