Introduction
The Quick Response Code (QR Code) is a two-dimensional barcode invented by Denso Wave Incorporated in Japan in 1994, aimed at solving product management issues in manufacturing and logistics industries. For me, however, because I often have to develop apps at work and provide customers with a download link, the download link is usually very long and inconvenient to manually enter on a mobile browser. But using QR codes can perfectly solve this problem. By generating a QR code for the app download link, and then using the built-in scanning function of a mobile or tablet browser to scan it, the link address in the QR code is automatically recognized and the download starts automatically. At the same time, in order to distinguish between different apps' QR codes, I also need to be able to standardize the app's name and a brief description at the bottom of the QR code image. In this way, creating one image and then sharing it with customers is very convenient.
