Introduction
Recently, two-dimensional QR codes, which are the newest development of Japanese programmers from the company “Denso-Wave”, have begun to gain increasing popularity. For the first time the QR code was used in 1994 in the automotive industry. Over time, the QR code began to gain more and more popularity, the reason for which was an incredibly effective method, contributing to the almost perfect preservation of any encoded data. Today, a QR code can “hide” absolutely any information, be it a link to a web resource, a phone number, an e-mail address or even a huge text with a thousand characters.
Like any other program that implies encryption of information, a QR code must have a method of subsequent decryption. The person to whom the data was intended will be able to see the contents only after it has scanned and read the encrypted message. It is important to know that practically any modern smartphone can easily cope with this seemingly very difficult task.
Scanning principle
Initially, the user of the newfangled gadget should learn how to scan the QR code. And for this he will need a built-in camera of the mobile device. After the picture has been photographed, the specialized software package will be able to recognize the QR code with high accuracy - in particular, by clearly displaying it can decipher the information hidden under it.
In the article below, we will try to consider the principle that allows you to scan the QR-code by means of programs that can be installed in the iPhone OS and Android. It should be noted that mobile devices that run on these operating systems can belong to absolutely any manufacturer.
A program that helps recognize information
IPhone OS
Despite the many functions that the modern smartphone is endowed with, there is no program in the list of standard applications that can help the iPhone to contact and influence the QR code. In order for the gadget to be endowed with specific functions and scan, you need to perform a few simple steps.
To be able to enjoy all the benefits of a specific program, you need to find a resource in the AppStore that helps download QR Reader, a program developed by TapMedia. Despite the fact that anyone can download this application for free, during the work you will have to watch several self-contained commercials.
After downloading the product must be installed. To do this, the user must launch it and position the viewfinder, equipped with a red bar, moving across the screen of the gadget, directly above the readable QR code. Specific imitation of the infrared beam helps to customize special scanners.
In order to recognize the data as quickly as possible and, importantly, accurately, the code must have a good image. Only a high-quality scanned image will help to recognize the data and, as a result, display previously encrypted information.
Using a specialized software product is quite simple, since the embedded code will allow you to automatically perform the functions embedded in it. In other words, if the QR code hides the link to the electronic resource, then a site encrypted with a code will open in front of the user through the integrated web browser.
Android OS
From a practical point of view, the principle of operation of a typical application in a mobile device operating on the Android platform is no different from what works in the iPhone OS. The user of the gadget should go to the “Play Store”, using a search engine to find actions similar to the “QR Reader”.
After installing on Android, QR Reader needs to be launched, and with the method described earlier, try to “catch” the QR code with the built-in viewfinder. The scanner can be tracked on a moving red bar.
At this stage, the "manual" user work is completed. After the response of the software product indicating successful receipt of the code, the acquired data will be decrypted, and the smartphone will automatically be able to reproduce the “hidden” actions.
It should be noted that in the article one of the most frequently used programs is given for example, which helps to quickly recognize a QR code. In fact, in the expanses of the worldwide network, you can find a lot of typical developments that will just as well cope with the tasks assigned to them. Surely after using several options, the user will be able to choose his or her most acceptable product.
Conclusion
You should not assume that a QR code can scan only a smartphone, because most of stationary computers have the same capabilities. True, the PC will be able to scan single codes. Therefore, if necessary, to regularly work with large amounts of hidden information, it is best to purchase a specialized hand-held scanner that is connected to the computer via the USB output. Such a device is very effective in operation and is characterized by quick response.
