What Does Quick Response Code (QR Code) Mean?
A quick response code (QR code) is a type of two-dimensional bar code that consists of square black modules on a white background. QR codes are designed to be read by smartphones. Because they can carry information both vertically and horizontally, they can provide access to a vast amount of information, including links, text or other data.
QR codes were created by Denso Wave, a Toyota subsidiary, in 1994. Although they were initially used to track parts in vehicle manufacturing, their use in mobile phone applications continues to grow. They are often found on signs, in print publications, on business cards or in any context where users might seek additional information.
In the past, consumers had to download a special reader in order to interpret a QR code. Today, consumers can simply point their smart phone or tablet's camera at the QR code, and the camera's software will automatically interpret the information the code contains. This capability helped broaden the way people used QR codes to share information and make contactless payments during the COVID-19 pandemic.
