What does QR stand for in codes scanned by cameras?

Quick Response

QR stands for Quick Response. The name was chosen to emphasize how fast a camera can read and decode the information stored in the two-dimensional code, so you get immediate access to the data (like a URL, text, or product details). Historically, the R represents “Response,” highlighting the rapid feedback the code provides when scanned. The other expansions don’t reflect the established meaning or the purpose of the code, which is about speedy decoding rather than anything like “Quick Read” or “Quality Resource.”
