Abstract

A disclosed method comprises scanning a radio-frequency identification (RFID) tag on a package to generate scanned data, and generating a handling instruction for the package based on the scanned data. The handling instruction can be executed to route the package to a tip position within a hub facility for directing the package to the next location along its route, and/or to pre-load the package in a vehicle for delivery to the package'"'"'s final destination. Related systems and computer-readable media are also disclosed.
