What is a QR Code?
A Quick Response code, commonly referred to as a QR code, is a type of 2D barcode that stores information such as text, URLs, email addresses, phone numbers, and even geographic coordinates. These codes were invented in the 1990s by Masahiro Hara of Denso Wave, intended for use on company products, parts, and inventory.
QR codes are used in various industries, including marketing, advertising, healthcare, education, and more. They can be found on business cards, posters, flyers, magazines, and even on buildings and street signs.
