KM 2.0 is a service for small agricultural producers also focused on environmental health. Zero kilometer food, in addition to being environment-friendly, allows you to obtain fresh food that better preserve their nutritional properties. The KM 2.0 project helps the small producers to compete with big markets. The customers can exploit the app to buy products from the short supply chain implemented by the producers with the app itself and decide which locker to use for receiving their order, e.g., the one closer to their home. The idea behind this project was born during the COVID-19 pandemic, to enable contact-free shopping for the short-supply chain.
