1. A package management system comprising:
a camera that captures images of a location;
a data-capture device configured to acquire identification information associated with a given package;
a weight sensor operatively configured to measure weight of packages; and
at least one processor in communication with the data-capture device and the weight sensor, the at least one processor configured to:
receive from the data-capture device the identification information associated with the given package,
determine, based on the weight measured by the weight sensor after the data-capture device acquires the identification information associated with the given package, an occurrence of a weight change at the location,
expect a next package to be placed at the location where the weight sensor can measure the weight of the next package or removed from the location to appear next in the captured images and be the given package to which the identification information is associated;
associate a change in the captured images with the placement of the next package at the location or removal of the next package from the location;
compare where the change appears in the captured images with the location where the weight is measured by the weight sensor;
if, in response to the comparison and further in response to receiving the identification information associated with the given package, the next package expected to be placed at the location is the given package and if the weight sensor corroborates the identification information received by the data-capture device by detecting a weight change at the location that is an increase in weight, register the given package as being located at that location, and
if, in response to the comparison and further in response to receiving the identification information associated with the given package, the next package expected to be removed from the location is the given package and if the weight sensor corroborates the identification information received by the data-capture device by detecting a weight change at the location that is a decrease in weight and the given package was previously registered as being at that location, confirm proper removal of the given package from the location.
