A QR code (Quick Response code) is a two‑dimensional barcode that stores information in a grid of black and white modules. Unlike traditional barcodes that only read horizontally, QR codes work in two dimensions - allowing them to hold hundreds of times more data.
Denso Wave invented QR codes to track car parts. They made the patent public - that's why QR codes are everywhere today.
A single QR code can hold a full page of text: URLs, vCards, WiFi credentials, emails, calendar invites, and more.
Reed‑Solomon error correction means your code stays scannable even if torn, dirty, faded, or partially covered by a logo.
iOS 11 (2017) and Android 9 (2018) added native QR scanning to the default camera app. That's over 6 billion devices ready to scan.
