QR codes are two-dimensional barcodes. They were created in 1994 by an automotive industry in Japan to track vehicles during manufacture, allowing high-speed component scanning.

20+ years later, QR codes have become the most cost-effective technology to link the physical and digital worlds together.

By scanning a QR code, you 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.
