QR codes, or Quick Response codes, are two-dimensional barcodes that can store a wealth of information in a compact format. Originally developed in 1994 by Denso Wave, a subsidiary of Toyota, QR codes were designed to track automotive parts during manufacturing. However, their versatility has led to widespread adoption across various industries, from marketing to logistics.
Unlike traditional barcodes, which can only hold a limited amount of data, QR codes can store URLs, text, contact information, and even payment details. This capability makes them an invaluable tool in the digital age, where quick access to information is paramount. The structure of a QR code consists of black squares arranged on a white grid, which can be scanned by devices equipped with cameras.
The data encoded within the QR code is read by interpreting the pattern of these squares. The error correction feature embedded in QR codes allows them to be scanned even if they are partially damaged or obscured. This resilience is one of the reasons for their popularity; users can rely on QR codes to function effectively in various environments, whether on a printed flyer or displayed on a digital screen.
As technology continues to evolve, the applications of QR codes are expanding, making them an essential component of modern communication and commerce.
