The role of bar code in package extraction

　　When the package is delivered to the owner, the current way is that the owner must take the original delivery note. The original bill of delivery is often mailed to the consignee through the post and telecommunications department, which may cause that the package has been delivered, the bill of delivery has not been delivered to the shipper or the mail is lost, bringing a lot of trouble to the shipper. The use of barcode technology can be delivered by the owner of the private contract, that is, the use of encrypted barcode.

　　Details such as those containing the consignee's secret order required to check the package upon delivery. Scan the barcodes on the luggage package or on the pick-up card held by the consignee. The railway and the owner of the cargo input their passwords, check the identity information of the consignor and the consignee, complete the delivery of the package, and automatically update the information to the delivery package database, reduce the possibility of wrong claim, false claim.

　　The method of consignor's self-defined secret contract extraction is the evidence of consignor's self-defined package extraction at the time of delivery. After delivery, the shipper only needs to tell the consignee the extraction key. Once the package arrives at the station, the consignee can immediately extract the package according to the secret contract, without sending the delivery certificate and other delivery documents to the post and telecommunications department. The consignee can only pick up the package after obtaining the original bill of lading, which will greatly shorten the period of acceptance, transmission, transit, arrival and delivery of the railway package.

　　In fact, after the realization of computer network information management and sharing of the whole road package, through the reform of the package management and management mode, we can completely cancel the receipt of goods. It simplifies the pick-up procedure, speeds up the delivery of packages, and improves the image of railway packages transportation by means of secret pick-up contract.

　　Therefore, by improving the information representation of package transportation and adopting bar code technology, the operation efficiency will be greatly improved.
