Despite having been around for decades and receiving much media attention, QR codes never became the revolutionary mobile marketing tool that businesses and marketers had hoped.

This game-changing move allows QR codes to be scanned on Apple devices directly through the camera app. And the fact that the QR code feature is in the control settings enables ease of use. The latest Android smartphones have also made QR code scanning a native feature. This addresses the major barrier for QR code use in Western markets.
