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 )
