What is the QR Code and how to use it

What is the QR Code QR Code

We will explain what the QR Code is, how it can be used and how it can be generated. The QR Code is a code that, after being photographed, read, interpreted and decoded on the mobile phone, is sent to the Internet. In that decoded message, may be the URL of a website or the location of something that may interest you. It can be, for example, the restaurant menu we are in, a PDF file that is downloaded on the mobile phone or the promotion of a product.

What is the QR Code

QR Code is an abbreviation for Quick Response Code or QR Code.

It is a kind of barcode invented in 1994 by a team from Denso Wave.

While the barcode is one-dimensional, the information in the QR Code can be encoded either crosswise or longitudinally, in two dimensions, therefore.

This two-dimensional code can store a greater amount of information, in a smaller area and with the possibility of being able to be read faster than the bar code.

A Dense Wave waives the rights of your patent and therefore, this code can be used universally and free of charge. However, the QR Code is a registered trademark of this company.

It can be used on mobile phones that have a camera and an application that can read and convert it.

The application installed on the mobile phone recognizes the image of the QR code and converts it into characters.

These characters can be a URL address, a phone number, an electronic address (email), a georeferenced location or even an SMS.

How to get the QR Code App to be able to read the Code

To obtain this application, just click on the application store icon of the Smartphone's operating system, for example the “Play Store”.

In the Play Store, we look for the application using the word “QR Code”.

We select the application and finally click on the install button.

The application icon is thus created on the Smartphone's desktop.
