 Introduction: what is a QR code?
A QR code (abbreviated from Quick Response code) is a type of matrix barcode, that uses standardized encoding to contain information about
the item to which it is attached.

Where and How to use a QR Code?
The QR code can be applied on Static Billboards and on Digital Screens. The user can simply point their phone camera at a QR code and be
automatically redirected to the browser with the web page, which is a distinct new advantage since they neither have to download an
application anymore, nor type a URL. There are a number of practices when it comes to scannability of the QR code.

Why use a QR code?

● QR codes generates a strong call to action for the user.
● Can create Augmented Reality (AR) activations with Darabase.
While COVID has taught the populations of many countries what QR codes are and what to do with them, it is always advisable to explain both
that they need to be scanned and what the benefit of doing so is. The incentive for scanning should be clear or fewer people will do it. The
bigger the incentive, the higher the scan rate.

1. Right size
The further away the target QR code is from the user the larger it will need to be. As a rule of thumb a QR code should have a ratio of 1:10 with
the distance for a native camera.

2. Contrast
It is important to use a high quality image of the QR code in the print and always try and use high contrasting colours in your design. QR code
scannability is directly affected by contrast and sharpness of the final image.
Black on white is ideal but other options are possible.

3. Use a single QR code for content intended for further distances
Use a single QR code per creative. When a camera has more than one QR code in its viewport, it will jump focus around each of the QR codes.

4. Framing and the “quiet zone”
For maximum scanning success, QR codes need to be surrounded by a “quiet zone” of approximately 15% of the QR code dimension on each
side. This is an empty area around the sides of the codes that help the camera recognize the code itself. Without this, the code may not be
recognized and the scan may not be completed.

5. User context: Show the QR for as long as possible
Consider the time it takes for a person to walk on a sidewalk or in a mall, see content on digital signage, notice the QR, decide they want to
scan it, and successfully do. Designers should present the QR code for the full length of the spot.
