QR Codes

What are QR Codes?

“QR” (or “quick response”) codes store information in the form of a two-dimensional square barcode. QR codes direct users to mobile websites or videos, store text or contact information, call a phone number, and/or send text messages and emails.

People interact with QR codes by scanning the barcode with their mobile phone camera with an app. A QR reader application is needed to detect the QR code. You can download a QR reader application to your smartphone through a mobile application store. It is possible to track when, where, and how many people are scanning QR codes with Google Analytics,, and other services.
