Everything to know about QR Codes

A QR Code (Quick Response Code) is a two-dimensional barcode that can store and encode information in a grid of black squares arranged on a white background. Unlike traditional 1D barcodes, which store data in a single horizontal line, QR Codes use both horizontal and vertical space, allowing them to hold significantly more information. They can store various types of data, including URLs, text, contact details, payment information, and more. QR Codes are designed for quick and efficient scanning using smartphones, tablets, or dedicated QR scanners. Each QR Code follows a specific encoding pattern, with built-in error correction that ensures readability even if the code is slightly damaged or partially obscured.

The structure of a QR Code consists of key elements such as position markers, alignment patterns, timing patterns, and a data area, all of which contribute to its fast and accurate decoding. Thanks to their versatility, ease of use, and ability to store rich data, QR Codes have become a widely adopted tool for digital interactions and automation.

Who invented the QR Code?

QR Codes were invented in 1994 by Denso Wave, a subsidiary of Toyota, to streamline vehicle and parts tracking in manufacturing. Today, they have expanded into various industries, offering fast and contactless access to information.
