What is a QR code and how does it work?
A QR code, or Quick Response code, is a type of barcode that contains information such as text, URLs, or other data. It works by using a matrix of black and white squares to encode the information, which can then be read by a QR code scanner or a smartphone camera.
QR codes have become increasingly popular due to their ease of use and versatility. They can be used for a wide range of applications, such as tracking inventory, sharing information, or making payments. When a QR code is scanned, the encoded information is decoded and displayed on the device, allowing users to access the content or complete a specific action.
