What is a QR Code?
A QR Code, short for Quick Response Code, is a two-dimensional barcode that consists of black squares arranged on a white background. These codes are widely used to store and retrieve information quickly using a smartphone or a QR Code scanning app. QR Codes can contain various types of data, such as website URLs, contact information, product details, event details, or even Wi-Fi login credentials.
QR Codes were first developed in 1994 by a Japanese automotive company, Denso Wave. Initially used for tracking parts in vehicle manufacturing, these codes quickly gained popularity due to their ability to store large amounts of data in a compact format.
Today, QR Codes can be found everywhere – on product packaging, billboards, posters, restaurant menus, business cards, and more. They have become an ubiquitous part of our daily lives, providing a convenient way to access information or perform actions without the need to manually enter or search for it on a device.
QR Codes are so versatile that they can be scanned and decoded by virtually any smartphone with a built-in camera. All you need is a QR Code scanning app installed on your smartphone to unlock the potential of these powerful codes.
