QR Codes are two-dimensional barcodes. They were created in 1994 by an automotive industry in Japan to track vehicles during manufacture. They were designed to allow high-speed component scanning.
20+ years later, QR codes have become the most cost-effective technology to link the physical world with the digital world.
By scanning a QR code, the user can get instant access to a URL, a vCard, a YouTube video, a social network or even download a file, get a discount coupon or perform a PayPal payment.
QR code uses are infinite and that is what makes them so unique. Grand examples are Toronto’s music-linked QR codes on street corners and Antwerp’s implementation of QR codes for public transportation.
