History of QR Codes

QR codes were invented in 1994 by a Japanese company called Denso Wave. The company was looking for a way to track auto parts during the manufacturing process and wanted a code that could store more information than a traditional barcode. The result was the QR code, which stands for Quick Response Code. Initially, QR codes were primarily used in Japan for tracking and inventory purposes. However, as smartphones became more prevalent, QR codes began to gain popularity as a way to quickly access digital content. Today, QR codes are used in a variety of industries, from marketing to healthcare.

Design and Structure of QR Codes

QR codes are two-dimensional barcodes that are designed to be read by a smartphone camera. Unlike traditional barcodes, which can only store a limited amount of information, QR codes can store up to 7,089 characters of alphanumeric data. QR codes are made up of a series of black and white squares arranged in a grid pattern. The squares are read by a smartphone camera, which translates the pattern into digital information. The code also contains several alignment and timing patterns, which help the camera to accurately read the code, even if it is slightly distorted or damaged.

There are several different types of QR codes, each with its own structure and encoding method. The most common type of QR code is the standard QR code, which can store up to 3,000 alphanumeric characters. There are also QR codes that can store more information, such as the Micro QR code and the iQR code.
