QR Code (abbreviated from Quick Response Code) is a 2D matrix barcode that stores data. It was developed in the early 2000s by Japanese company Denso Wave with the purpose of tracking parts in vehicle manufacturing. Today, QR Codes have become incredibly popular in the digital world and are often used for encoding alphanumeric information, such as website URLs, for sharing on the internet.
A QR Code consists of square block modules, arranged in a square grid pattern on a white background, and typically contains some statistical error correction. QR Codes are read by a cell phone with a camera using a special app. Once scanned, the app translates the code into a class of machine-readable information, such as web address or text.
QR Codes are frequently used in marketing and advertising campaigns to drive people to website links or to make a purchase. Companies may also use QR Codes on business cards or other documents to provide contact information. They can also be used for redirecting to social media data or Wi-Fi login information.
QR Codes are slowly becoming an integral part of our interconnected digital lives, offering a convenient way for users to store and access essential information.
