Quick Response (QR) code is a two-dimensional barcode that can be read using a QR code reader or scanner. QR codes can store a large amount of data and are commonly used for marketing, advertising, and product tracking.

QR codes consist of black and white squares arranged in a specific pattern. The pattern can be read by a QR code reader or scanner to extract the encoded data. The encoded data can be a website URL, text, email address, phone number, or any other information.

QR codes are widely used in mobile apps and can be generated using various programming languages and libraries. QR codes can also be generated online using various websites that provide QR code generation services.
