What is a QR code and how does it work?
A QR code, or Quick Response code, is a type of barcode that stores information, such as text, numbers, or URLs, in a two-dimensional pattern of black and white squares. When a QR code is scanned, the information is read and decoded, allowing the user to access the stored data. QR codes are commonly used for various purposes, including marketing, payment, and authentication. They can be found on product packaging, advertisements, and even business cards.
The working principle of a QR code is based on the way it is scanned. When a QR code is scanned using a smartphone or a dedicated QR code scanner, the device’s camera captures an image of the code. The image is then processed using specialized software that decodes the pattern of squares and retrieves the stored information. The decoded information is then displayed on the device’s screen, allowing the user to access the linked content, website, or perform a specific action. In the case of Huawei devices, scanning a QR code is a straightforward process that can be completed using the built-in camera app or a third-party QR code scanner.
