Overview
QR codes contain data for a locator, an identifier, and web tracking, and use four standardized modes of encoding: numeric, alphanumeric, byte or binary, and kanji. The QR code was initially used in the automotive industry, but it soon gained popularity in other fields due to its ability to store a large amount of data in a small space. QR codes are used by major companies such as Google, Amazon, and Facebook for various purposes including product tracking and customer engagement.
🎵 Origins & History
The QR code was invented in 1994 by Masahiro Hara, an engineer at Denso Wave, a Japanese company. The QR code was initially used in the automotive industry, but it soon gained popularity in other fields due to its ability to store a large amount of data in a small space. For example, Toyota and Honda use QR codes to track parts and manage their supply chain.
⚙️ How It Works
A QR code works by using a two-dimensional matrix of black and white squares to store data. The data is encoded in the QR code using one of four standardized modes: numeric, alphanumeric, byte or binary, and kanji. The QR code is read by an imaging device, such as a camera, which uses Reed-Solomon error correction to extract the data from the QR code. For example, Apple's iOS operating system has a built-in QR code reader that can scan and process QR codes using the device's camera.
