Undersökning av möjligheter till optimering av CashComplete

Sammanfattning: This thesis work was done in the SCAN COIN headquarters in Malmö, Sweden. In the work, we investigate the possibility to optimize the product SCAN COIN CashComplete POS. CashComplete is a closed system that makes it easy to pay with notes and coins and get the correct change back. To make CashComplete more attractive in a self-checkout environment the products price must be decreased. This work focuses on reducing the price of the device for PC and power supply. The main costs consists of a motherboard with an integrated processor, an adapter for the computer to communicate with coin and note units, and two power supplies. As a replacement for the computer the possibility of using a single-board computer was examined. The compatibility was analysed and the performance was tested to determine if the system still is functional. Alternative adapters to communicate with the CAN interface was examined. To replace the power supplies measurements of power consumption for all units was made. The result was that the system works equally well with the single-board computer Raspberry Pi 2 and performed even better in some tests. The CAN adapter was replaced with a cheaper alternative. The power supplies was replaced with one power supply to supply all units. A functional concept model was created where the total cost has been decreased and the size of the chassis reduced.
