AI overview
A QR code is a square barcode made of black and white squares that was invented in 1994 to track car parts, and it can be read by cameras and smartphones. The code stores information in its pattern, which is extracted using special error-correction technology that allows the code to be readable even if it's partially damaged or unclear.
