How QR Code Works?

A QR Code works in the same way as a Barcode. It is basically a machine-scannable image that can instantly be read or scanned using a Smartphone camera.
When your Smartphone scans this code by the camera, it decodes the information which is stored in a QR Code in a human-readable language. If you have ever scanned a QR Code, you will be noticed that they can be scanned very quickly (scanned within few seconds). This makes QR Code very simple to access the stored data quickly.
