At the same time, you will immediately see the description in the code.

Actually, all. Install the application and scan QR codes that you meet. Perhaps you will find something interesting in them.

Recently, two-dimensional QR codes have begun increasingly popular, which are the latest development of Japanese programmers from the company DENSO-WAVE. For the first time, the QR code was used in 1994 in the automotive industry. Over time, the QR code began to gain increasingly popularity, the reason for which it became an incredibly effective method that promotes almost the perfect preservation of any encoded data. To date, the QR code can "hide" absolutely any information, whether it is a link to the web resource, a phone number, e-mail address Or even a huge text with a volume of thousand characters.

Like any other program that implies information encryption, the QR code must have a method of subsequent decryption. The person who intended the data can see the content only after scans and read the encrypted message. It is important to know that with this, at first glance, a very difficult task, can easily cope with almost any modern smartphone.

Scan principle

Initially, the user of the new-fashioned gadget should learn how to scan the QR code. And for this it will need a built-in mobile camera camera. After the drawing is photographed, specialized software package It will be able to recognize the QR code with high accuracy, in particular, by changing the display, decrypt information under it.

In the article below, we will try to consider the principle that will allow you to scan the QR code through programs that can be installed in OS iPhone and Android. It is worth noting that mobile devicesthat work on these OS can belong to absolutely any manufacturers.

Program to help recognize information

OS iPhone.

Despite the many functions that are endowed with a modern smartphone, in the list standard applications No program capable of helping iPhone contact and influence QR code. In order for the gadget to endow specific features and scan, you need to perform a few simple actions.

To get the opportunity to enjoy all the advantages of a specific program, you need to find a resource in the AppStore to help download "QR Reader" - a program, the developer of which is TapMedia. Despite the fact that anyone can download this application for free, during operation you will have to browse yourself several times the included commercials.

After downloading, the product must be installed. To do this, the user must run it and arrange the viewfinder equipped with a red stripe moving around the gadget screen directly above the readable QR code. Specific imitation of the infrared beam helps customize special scanners.

In order to recognize the data could be as quickly as possible and, which is important, for sure, the code must have good image. Only a qualitatively scanned picture will help recognize the data and, as a result, display previously encrypted information.

Use the specialized software product is quite simple, since the built-in code will allow automatic mode Perform the functions laid in it. In other words, if the QR code hides the link to electronic resource, Before the user, through the embedded web browser, a few seconds will open the site encrypted code.

OS Android

From a practical point of view, the principle of operation of a typical application in a mobile device operating on android platform, it does not differ from what works in OS iPhone. The user of the gadget should go to " Play Market", Through the search engine, find similar on the principle of the action" QR Reader ".

After installing on Android, "QR Reader" you need to run, and the method described earlier to try to "catch" the built-in viewfinder QR code. The scanner operation can be traced along the moving red stripe.

At this stage, the "manual" work of the user is completed. After the response software Product, indicating the successful acquisition of the code, the acquired data will be decrypted, and the smartphone in automatic mode will be able to reproduce "hidden" actions.

It is worth noting that the article provides for example one of the most frequently used programs that helps quickly recognize the QR code. In fact, a lot of typical developments can be found on the expanses of the World Wide Web, which with the same success with the tasks assigned to them. Surely after the operation of several options, the user will be able to choose its most acceptable product for it.

Conclusion

It should not be assumed that the QR code is able to scan only the smartphone, because most stationary computers have the same capabilities. True, the PC will be able to scan unit codes. Therefore, if necessary, it is best to work with large volumes of hidden information, it is best to purchase a specialized manual scanner connected to a computer via USB output. Such a device is very efficient in operation and is distinguished by the speed of the response.

You can not meet in the Internet of a person who did not hear about QR codes at least the edge of the ear. With the increased popularity of the network in recent decades, users needed to transmit data from each other different ways. QR codes are just a "peddle of" information that the user was encrypted there. But the question is in the other - how to decipher such codes and get what is in them?

If earlier the user had to look special applicationsHelping to decrypt the QR code, then nothing is required, except for the availability of Internet connections. Below we will look at 3 ways to scan and decrypt QR codes online.

Method 1: ImGonline

This site is one large source that has everything to interact with images: processing, size changes, and so on. And, of course, there is an image handler with QR codes that interests us that allows for recognition to change the picture as we are pleased.

To scan an image of an interesting, follow these steps:

Method 2: Decode IT!

In contrast to the previous site, this is fully based on what helps users in the network decrypt great amount Data types, ranging from ASCII characters and ending with MD5 files. It has a rather minimalistic design, which allows you to use it from mobile devices, but it does not have any other functions that help decipher QR codes.

Now you can meet a two-dimensional image consisting of white and black squares. It is called QR -Kod. With the help of a tablet, computer or smartphone, you can decode this image to get any information. QR-Codes are used to advertise companies, placement of the Rules of Special Proposals for Customers and the transfer of other information. Now such codes are printed even on supermarket checks, so that buyers can keep shopping lists and receive bonuses through special mobile applications. We will figure it out how to decrypt this code, having a computer or smartphone at hand. Decoding with a tablet does not differ from the one that is produced by a smartphone, so we will not consider it in detail.

How to scan the QR code using a computer?

Previously, to decrypt QR -Codes using a computer, it was necessary to purchase a special scanner connected via USB. Now there are several programs and online services that allow you to decipher information from QR -Code. We give the best options.

Online scanner

To use this method, you need to have you to visit the site to recognize the image with the QR code. There are two recognition options on the site:

In advertising purposes, references to Internet resources are usually given, but you can encode and link to download the application. Most often, the developers placing utilities in open areas are given, and then making explanatory texts.

Windows Phone application

The best application for reading codes for phones based on operating system Windows is the usual string search engine Yandex. It can assume any code, regardless of the plane plane. At the same time, you do not need to press anywhere so that the reading began is to simply bring the camera to the code. The logging and use of the information received only on the user's request.

After reading the information, you will see a screen with a snapshot of the code, and the decrypted information will be indicated under it a small font - link, telephone number or address. You can find out the details if you click on the string that appears. The link on the link opens the site, finds the address in Yandex maps, offers to dial a phone number or write a message on it.

For phones on Windows OS there are also many and other applications, including the analogues of utilities for other operating systems. But the main problem of programs is a long triggering, lack of support for developers, errors during operation. For this reason, the utility embedded in the Yandex search string is the best for technology with this operating system. Especially it is Russified and understandable.
