A QR code is a type of barcode that can be read easily by a digital device and which stores information as a series of pixels in a square-shaped grid.

How do I scan QR codes?

1.Open the QR OFFERS application or the camera on your smartphone.
2.Point it at the QR code – you should be able to point your camera from any angle and still receive the necessary information.
3.The data will be instantly shown on screen – for instance, if the QR code contains contact details, your phone should instantly download these.

How do QR codes work?

The patterns within QR codes represent binary codes that can be interpreted to reveal the code's data.

A QR reader can identify a standard QR code based on the three large squares outside the QR code. Once it has identified these three shapes, it knows that everything contained inside the square is a QR code.

The QR reader then analyzes the QR code by breaking the whole thing down to a grid. It looks at the individual grid squares and assigns each one a value based on whether it is black or white. It then groups grid squares to create larger patterns.
