Understanding QR codes
QR (Quick Response) codes are two-dimensional codes that can be read by QR code readers or scanners. These codes represent an evolution in data encoding as they can store much more data than barcodes. QR codes can store various types of data, including URLs, text, images, and even audio and video files. They are made up of black and white squares arranged on a white background. QR codes were first created in 1994 by Denso Wave, a subsidiary of Toyota.
The importance of scanning QR codes
QR codes are everywhere – on billboards, posters, product packaging, restaurant menus, and more. Scanning these codes can provide access to valuable information that can be helpful for marketing, advertising, and communication. For example, a QR code on a restaurant menu can take customers to the restaurant’s website or menu, while a QR code on a product package can provide customers with product details or promotional offers. Scanning QR codes is also becoming an important way of contactless payment, with popular mobile payment systems such as Alipay and WeChat using QR codes as part of their payment process.
