Patent WO-2018073667-A2 (WO)
Inventor: SWANSON KATHERINE
IPC: H04W4/00
Filed: 2017-09-11
Abstract: A courier management system receives an order request from a requesting device including a list of requested items and a delivery location. The courier management system creates an order entry by selecting a source location and a courier for the order. The courier management system sends order information from the order entry to a courier device of the selected courier and a source device corresponding to the source location, where the order information includes an order ID, a source ID, and a courier ID. The source device broadcasts a beacon including the source ID and the order ID. The courier device detects a short range beacon signal from the source device and determines whether the detected source ID and order ID match the received source ID and order ID from the order information. Responsive to a successful match the courier device verifies its proximity to the source device.
