A QR code, short for Quick Response code, is a two-dimensional barcode that contains information that can be quickly and easily read by a QR code scanner or a smartphone camera. QR codes can store various types of data, such as website URLs, text, contact information, Wi-Fi network credentials, and more. They are commonly used for marketing, advertising, payments, event ticketing, product packaging, and other applications where quick access to information is desired. When scanned, the QR code typically triggers an action, such as opening a website, displaying text, or adding contact information to a phone's address book.
