Abstract: The present disclosure relates to a system and related methods for automatically managing the last mile phase of package and parcel deliveries. This is achieved by automatically detecting tracking information on the user device of an individual having access to a smart locker and generating a reservation record and smart contract for the delivery. The courier scans the parcel at the appropriate smart locker, which verifies that the package matches a reservation record and can then take a set action, unlocking the smart locker door or initiating a call with a recipient or peer. The cost efficiency of the last mile phase is thus drastically improved, increasing supply chain certainty and reducing the need for repeated deliveries.
