What is QR Code?

QR Code is a 2D barcode. When scanned via the camera of mobile devices, it is decoded and becomes a passage of text or link that redirects the user to a website.

The QR Code is a way to add data to limited spaces. For example: a label of food can provide nutrition information or recipes if you have the QR Code enabled. A business card can refer to an institutional video when its QR Code is applied.
