Filed: 2018-10-07
Abstract: The number of used delivery services has increased as the internet shopping malls have become active. However, because private information such as the names, the addresses, the phone numbers, and the like of receivers is printed on the transportation letters for delivery and is attached to package boxes, for the delivery services, the private information is easily exposed as anybody can recognize the private information at the glance of the transportation letters. In particular, when delivered goods are deposited in a convenience store or a management office of the apartment as a customer cannot directly receive the goods, the possibility of revealing the private information further increases. Of course, the private information may not be printed but the delivery information may be inquired from a server by using the transportation number whenever necessary. But, for this, the delivery service person has to access the internet. The delivery service person may be located at a site at which the internet is not available and the load of the server has to be increased if the delivery information is inquired whenever necessary. In recent years, many people use smartphones and the smartphones basically function to scan QR codes. The present invention relates to a method and an apparatus for generating and printing QR codes instead of printing delivery information as plain characters in a transportation letter and inquiring delivery information by scanning the QR codes when necessary. According to the present invention, private information can be prevented from being revealed due to a transportation letter.
