Some restaurants print QR codes on edible rice paper or chocolate to link to menus, nutritional information, or the chef's story.
Educational institutions and event planners create QR code scavenger hunts where each code reveals clues or tasks for the next location.
QR codes can trigger AR experiences, bringing static images to life or overlaying digital content onto physical spaces.
QR codes were invented by Denso Wave, a subsidiary of Toyota, to track vehicles during manufacturing. The name "QR Code" stands for "Quick Response Code".
The QR code specification was released to the public, and the technology became an ISO international standard (ISO/IEC 18004).
QR codes began to appear in magazines, on business cards, and in advertising, but adoption was limited due to the lack of QR code readers on mobile phones.
As smartphones became ubiquitous, QR codes gained popularity. Apps specifically designed to read QR codes became available, and later, built-in camera apps added QR code scanning capabilities.
The COVID-19 pandemic dramatically increased QR code usage for contactless interactions, from restaurant menus to payment systems and contact tracing.
QR codes can still be read even if up to 30% of the code is damaged or obscured, thanks to error correction algorithms.
A single QR code can store up to 7,089 numeric characters or 4,296 alphanumeric characters.
The three large squares in the corners of a QR code help scanners determine the orientation and angle of the code.
A smaller version called Micro QR exists for applications where space is limited, with only one position detection pattern.
Thanks to error correction, QR codes can be customized with logos or designs while remaining scannable.
The largest QR code ever created was 36,100 square meters, made by Audi in 2013 using 159 cars arranged in a pattern.
