A QR code scanner is a software-based system that is used for reading and decoding QR codes from digital images. QR codes are two-dimensional barcodes that are typically used to store data such as URLs, contact information, or product information. QR code scanners use either an optical scanner or a camera to capture the code and then decode it. The scanner then displays the information contained within the code on the user's device. QR code scanners are widely used in a variety of industries, such as retail, healthcare, and logistics, to provide customers with easy access to product information. They are also used by businesses to track their products and inventory, or to provide customers with access to exclusive offers.
