QR Codes

What
QR stands for Quick Response. It's a 2 dimension barcode that was created in 1994 and is very common in Japan. Although there has been slow adoption in the States, exploding smartphone ownership has increased awareness.
Why
They allow for engagement and interaction. Think of them as an alternative way to input data into the phone. Calvin Klein has used QR codes on billboards, Gap has used QR codes at in-store Kiosks, and FOX has used them on TV. One way communication channels are now interactive.
How
All that is required is a barcode scanning app and the ability to recognize them. Download one below by selecting your device.
