A QR Code (Quick Response Code) is a two-dimensional square barcode which can store encoded data.
The data encoded is typically a URL link to a website, but can store other information as well. Someone with a mobile app or device that supports QR Codes can use that app's camera to scan QR Codes. Facebook, Apple, Twitter, Pinterest, Snapchat, Chrome, Samsung Internet, Bing, and others now all support QR Codes, making interacting with QR Codes easier than ever (see How do people see content through my QR Codes?).
With Phy, you can set up and manage QR Codes and fully control the content experience that appears across all of the above-listed app and mobile operating systems.
