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.
How do QR Codes work?
An active QR Code is one that a QR Code scanner is able to scan easily, prompting users to click on an external link upon scanning. The external link delivers relevant information that the user is looking for.
How to scan a QR Code

- Open the camera

The modern QR Code may seem very normal to the eyes but actually consist of 7 element parts. Like bar lines and patterns in 2-D barcodes, each part of a QR Code has a specific purpose. Each of these parts creates a sort of crossword puzzle-like pixel pattern. The specific elements hold information such as direction, timing, error tolerance, empty spaces. Learn more about these elements of a QR Code below.
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.
There are over 40 different QR Code versions. These are markers present in a QR Code that specifies the one that is being used. The most common ones are versions 1 to 7.
The format pattern consists of information about the error tolerance that makes it easier to scan the code.
Data and error correction module:
The central part of a QR Code consisting of black and white modules is where the code stores the data and has blank space surrounding them to allow up to 30% of the code to be damaged.
What are some QR Code features that make it unique?
High capacity encoding of data
Unlike standard barcodes that can store only 20 digits of data, QR Codes are capable of storing several dozens to several hundred times more data in them.
There is no one size fits all phenomenon with QR Codes. However, it is ideal to have the print size scannable by any smartphone with the capability. A size of 1 cm square or 0.4 inches square should be the minimum you should aim for.
Dirt and damage resistant
The error correction capability of the QR Codes enable it to recover the damaged part and make it readable. However, there is a limit to the damage that can be inflicted before it becomes unreadable by any type scanner.
The position detection markers make it possible to read the QR Code from any angle. The omni-directional and high speed reading capability make the QR Code unique from other barcodes.
Structured appending feature
A regular QR Code can be divided into multiple data areas. Similarly multiple data areas can be conversed to make a single data symbol. One data symbol can be divided into 16 symbols which allows printing in a narrow area.
