[0002] As we all know, a QR code scanner is a portable scanning device that is mainly used to quickly read QR code information. It captures the QR code image through an optical system, and then uses a built-in decoder to convert the image into recognizable data, such as text, links, phone numbers, etc. QR code scanners are widely used in retail, logistics, catering, medical and other industries, allowing users to quickly obtain information in the QR code.
