The code consists of a pattern of black and white squares arranged on a grid, with each square representing a binary digit (0 or 1). QR codes can store a variety of different types of information, including website URLs, contact information, and even entire documents.

Most QR code reader apps are available for free and can be downloaded from the App Store or Google Play. To scan a QR code, simply open the app and point the camera of your smartphone at the code. The app will automatically recognize the code and display the information that it contains.
