QR Code
QR Code stands for Quick Response Code and is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. QR Codes are now widely used in various applications such as product tracking, item identification, document management, and marketing due to their fast readability and greater storage capacity compared to standard UPC barcodes. This topic covers the creation, usage, and applications of QR Codes, including how they are generated and read by devices. It also explores the technology behind QR Codes, their standards, and their impact on industries such as retail, logistics, and mobile payments.
