What is a QR code and how does it work?
A QR code, or Quick Response code, is a type of barcode that stores information such as text, URLs, or other data. It works by using a grid of black and white modules to represent the data, which can be read by a smartphone camera or other QR code reader. When a QR code is scanned, the reader decodes the data and performs the desired action, such as opening a website or displaying a message.
QR codes are commonly used for marketing, advertising, and other purposes, and can be found on product packaging, business cards, and other materials. They are also used in mobile payments, such as Apple Pay and Google Pay, to facilitate transactions.

By scanning the QR code from your camera roll, you can still access the information or perform the desired action without having to find the physical QR code again.
