A quick response (QR) code is a two-dimensional barcode in which a lot of information can be recorded. There are many online QR code generators that conveniently make QR codes. Recognition of QR codes with a smartphone is easy and fast. Therefore, QR codes are widely used in various industries, such as manufacturing, logistics, transportation, retail stores, advertising, education, and office automation. This paper proposes the design of a QR code–based client–server tour guide system, which comprises a web server, a streaming server, and an archive system. The client is a smartphone application that recognizes the information in a QR code when the user takes a picture of it. Then, the client accesses the web resource designated by the QR code. A web site can provide a video closely related to the tourist attraction to which the QR code is attached. In addition to playing videos, the web site provides many kinds of useful information to tourists.
