Ans. QR code, short for Quick Response code, is a type of barcode that a smartphone camera can scan to access information. It’s a square matrix of black and white modules that can store various data, including URLs, text, phone numbers, and even small files.
Q. How were QR codes invented?
Ans. QR codes were invented in 1994 by Masahiro Hara and his team at Denso Wave in Japan to track automobile parts. The inspiration came from the game "Go," where the arrangement of black and white stones on a grid sparked the idea for a two-dimensional code that could hold much more information and be read from any angle, unlike traditional barcodes. Denso Wave later made the technology open-source and royalty-free, which was key to its widespread adoption.
