What do you mean by QR Code?
QR stands for Quick Response. First designed in 1994 for the automotive industry in Japan, QR codes have since
perpetuated into every industry and are used all over the world by consumers. It has started gaining a lot of
popularity with consumers since scanning QR codes does not require an app. The camera app in both Android and
iPhones is capable of scanning QR codes natively.
Elements of a QR code
QR codes may appear to be random but they are in fact slightly different. Although QR codes can be customized, the
shape of the QR code must always be square. There are 7 different elements in a QR code.
This indicates the direction in which the QR code is printed. Even if your camera is at an
angle, you will still be able to scan the QR code.
If the QR code is too large, say on a billboard, this helps to orient the image.
This helps the QR code scanner determine how large the data matrix is in the QR code.
This is the most crucial part of the QR code. This helps the QR code scanner differentiate the QR
code from the surroundings.
