The system housed inside the Vending Machine will collect data from the Vending Machine when a Technician / a valid person with the Android App + the right password connects to the RPi. This then allows them to download the data from the Machine and store it on the Android Phone / Tablet. The data is encrypted and cannot be edited or spoofed. The file is then uploaded to our secure servers and an accountant or manager can review the data such as coins in, coins out, coins stored, stock details, errors, and even temperature and humidity logs over time ( graph view )
