A QR code, short for Quick Response code, is a two-dimensional barcode that can be scanned using a smartphone or a QR code reader. It was first developed in 1994 by a Japanese company called Denso Wave, and has since become a popular way to store and share information.
QR codes can store a variety of data types, including text, URLs, contact information, and even multimedia files. They are often used in advertising, marketing, and product packaging to provide additional information or to direct users to a website or social media page.
To scan a QR code, users simply need to point their smartphone camera at the code and use a QR code reader app to decode the information. Many smartphones now come with built-in QR code readers, or users can download a free app from their app store.
QR codes are a convenient and efficient way to share information, and their popularity continues to grow. They can be found on everything from business cards to billboards, and are a valuable tool for businesses and individuals alike.
