When express parcels are transferred in the transit warehouse, they need to be checked and recorded one by one and communicated to the next site through the computer, which is time-consuming and labor-intensive. The consignee and consignor cannot check the real-time delivery status of the package; the number of goods received in the intermediate warehouse is not consistent with the number of goods shipped, or the goods are lost, the problematic link cannot be found when the goods are lost.
