You have probably already noticed colorful black and white squares on most products. Many do not even pay attention to them. In fact, this digital picture is called a QR code and contains useful information. This article details what a QR code is and how to use it.
What it is?
The QR code was originally used in 1994 in Japan to introduce goods accounting. This innovation turned out to be a very successful project and appeared outside the country in a short time. But, what is this QR code, and how to use it? In its structure, this is a digital picture, which is a block of encrypted text information. It was created as a two-dimensional implementation of the barcode, but unlike it, it contains much more information.
How to use a QR code on Android
In order to read it, a lot of programs have been developed for various devices, including Android. Almost all of these applications are free and freely available for download. The technology uses the well-known type of encryption, so any resource can help you.
Any device with a camera is capable of scanning information from a QR code; all you need is the necessary software. The main elements during scanning are search patterns. These are black squares in all corners and around them. They direct and enable the scanner of digital encryption not to get confused among all these points, as well as to find out its location in the visibility of reading. Everyone who wishes is able to create their own personal QR code by encrypting the necessary information in it. You can enter your personal data there within the size of this encryption, since the code itself is not dimensionless and will intervene in total up to 2953 bytes of data.
Finding a generator is also not difficult. This is usually the same resource that provides scanning services. To create your own code, you just need to give the program the information that you want to encrypt. Usually, new devices on the Android platform already have installed (wired) scanners and generators. And if this is not, you can easily download it in the "Play Market". There should not be a problem with choosing an application, since they all fully perform their functions.
Conclusion
We hope you find this article useful, and now you know how to use the QR code. We do not recommend downloading utilities for reading and generation on third-party resources, you can expose your device to malware infection.
