QR code: How to scan QR code on Android mobile phone, iPhone, and laptop

QR codes have several use cases, other than making payments. They can be used to track information, open web pages, and get details of someone’s social media profile, among other things. To get all that done, you need to scan QR codes. This can be done using your mobile phones as well as laptops. If you are not sure how to scan QR codes on an Android mobile phone, iPhone, or laptop, below is an easy step-by-step guide. While most devices come with QR code scanners built-in, there are several third-party scanners as well to get the job done.

What is a QR code?

A QR (Quick Response) code, in simple words, is a type of a two-dimensional form of the barcode (similar to barcodes seen on the back of packed products). It consists of black squares arranged in a square grid on a white background, which can be read by an imaging device such as a camera. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image. Now, that we have an idea of what a QR code is, let’s see how to scan it using various devices.
