Methods, apparatus, and systems for transmitting a corrective pickup notification for a shipped item accompanying an ID node moving with a courier away from a master node
Improved movement-based technical solutions for transmitting a corrective pickup notification for a shipped item are described. For example, a first master node at a first location receives shipping information about the item. That master node identifies an intended pickup master node from the shipping information and identifies the location of an ID node associated with the item over a time period, which may indicate the item is moving away from the first location. After identifying a courier master node accompanying the departing ID node, the first master node automatically senses an adverse pickup condition when the identified courier master node does not correspond to the intended pickup master node and the ID node's detected location over time indicates the item is moving away from the first location. The first master node then transmits the corrective pickup notification to a second logistics devices based on the adverse pickup condition sensed. |
