The Quick Response Code (the popular QR code) is the trademark for a type of matrix barcode, an optically machine-readable label that is attached to an item and that records information related to that item. It consists of black square dots arranged in a square grid on a white background, which can be read by an imaging device.
Initially designed for the automotive industry in Japan, this system has become popular due to its fast readability and greater storage capacity.
With the popularization of the smartphones, it has become a focus of advertising strategy, since it provides quick and effortless access to the brand’s website.
The best part is that you don’t need to be an expert in coding to create your own QR code. Google has a popular API to generate QR codes, and apps for scanning QR codes can be easily found on devices.
