What are QR codes?

QR codes are now everywhere we look, magazines, products, airlines are also slowly looking at bringing them into everyday use. So if you have been looking at these little squares of dots and might be considering using them in your marketing strategy, size is an important thing to take into account.

The first thing that has to be understood about a QR code is that it is usually read by the modern smartphone and so here are a few things to take into consideration. It is not the size of the code image that determines the minimum size at which the code can be scanned; it’s the size of the modules, these are the tiny black squares that make up the QR code or image. So to ensure that it is readable, it must not fall below the resolution limit for the camera on the smartphone.

The main consideration when determining the size of your QR code has to be the distance at which the camera will have to scan. To put this simply, the further the distance the camera is from the QR code, the smaller the code will appear in the camera viewing window. This will of course make the modules appear to be smaller, until the distance is increased so much that and the modules become so small that the image will not be readable.
