QRkoodeille

QRkoodeille, often referred to as QR codes, are a type of two-dimensional barcode that can be read by smartphones and other image scanners. The term "QR" stands for "Quick Response," reflecting their ability to be quickly scanned and decoded. These codes are designed to store information, such as website URLs, contact details, text messages, or Wi-Fi network credentials.

Invented in 1994 by Masahiro Hara of Denso Wave, a Japanese automotive company, QR codes were initially developed to track vehicles during the manufacturing process. Their widespread adoption outside the automotive industry began as smartphone usage increased, providing a convenient way to bridge the physical and digital worlds. Unlike traditional one-dimensional barcodes, QR codes can store a significantly larger amount of data and can be read even if partially damaged or obscured.

Scanning a QR code typically involves opening a camera application on a smartphone and pointing it at the code. The device's software then recognizes the pattern, decodes the stored information, and often prompts the user to take an action, such as opening a webpage or adding a contact. Their versatility and ease of use have made them a common feature in marketing, advertising, ticketing, and everyday information sharing.
