Whatsapp came with many new features with time and the most recent one is the introduction of Whatsapp QR code in its app. The first question here is what is a QR code and how does it work?
A bar code is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application.
A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used. A QR code consists of black squares arranged in a square grid on a white background, which can be read by an imaging device such as a camera, and processed using Reed–Solomon error correction until the image can be appropriately interpreted.
The required data is then extracted from patterns that are present in both horizontal and vertical components of the image. Before QR code it used to be a lengthy process to go to a specific website by typing the whole address of the website in search engines and then were able to visit the page.
But with QR codes it is now so much simpler and easier by just scanning the QR code and it takes you to the website in seconds.QR codes are usually used for advertising purposes to consumers. Generally, Smartphone is used as a QR code scanner that displays the code and converts it to some useful form (such as a standard URL for a website.
QR code was at first used to track parts in vehicle manufacturing. QR codes are used for a much wider range of applications. These include commercial tracking, entertainment, and transport ticketing, product and loyalty marketing, and in-store product labeling. Organizations also use QR codes to store their information and share it via QR codes.
QR codes that store addresses and URLs are imprinted on books, magazines, visiting cards, historical places, tombs, and gardens, basically every place that wants to share information.
People just have to scan the QR code in the scanner in their phones using inbuilt scanner or scanner apps to scan the code and it will take you to the related website, page, or information. This act of linking from physical world objects is termed hard linking or object hyperlinking. QR codes also may be linked to a location to track where a code has been scanned.
