QR codes were developed in 1994 by Denso Wave to store more data than traditional barcodes. QR codes use a two-dimensional design and can store thousands of characters compared to only 20 for barcodes. They are commonly found in magazines, on television, the internet, products, streets, and in libraries. QR codes allow smartphones to perform actions like opening webpages or adding contacts when scanned. Anyone can create a free QR code online as long as the landing page is mobile-friendly.
