Several years ago, so-called QR codes became an integral part of our lives; to read them you need a special program - a QR code scanner. They began to be printed on books, magazines, cookie packages, billboards, and generally wherever there was at least a little space.
These codes are a picture on which white and black squares are arranged in a special way. Actually, if you correctly read the location of these squares, you can decipher the code hidden in this picture. This is what the above-mentioned scanners exist for.
Let's consider which applications for Android are the most popular, and which of them are the most functional.

In general, of all similar programs, the development of Geeks.Lab.2015 has the highest rating on Google Play. User ratings are usually the best selection criteria.
Other features of this program are:
From the video below you will learn more about QR codes.
Nowadays you can find everywhere a two-dimensional image consisting of white and black squares. It is called a QR code. Using a tablet, computer or smartphone, you can decode this image to obtain any information. QR codes are used to advertise companies, post rules for special offers for customers and convey other information. Now such codes are even printed on supermarket receipts so that customers can keep shopping lists and receive bonuses through special mobile applications. Let's figure out how to decipher this code with a computer or smartphone at hand. Decoding using a tablet is no different from what is done with a smartphone, so we will not consider it in detail.
How to scan a QR code using a computer?
Previously, to decipher 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 a QR code. Here are the best options.
Online scanner
To use this method you must have You need to visit the website to recognize the image with the QR code. The site has two recognition options:
- Upload a picture with a QR code;
- Use the camera on your smartphone or laptop (the site will ask permission to access it).
This utility is located in the computer's memory. Its advantage is that you do not need to prepare an image with code in advance. It is distributed free of charge and can be installed in just a few minutes.
After launching the program, you have several options: read the code from a file (photo or sent document), use a webcam for this, or take it directly from the screen. If you choose the second option, then you need to open the site or file and highlight the QR code using a frame. After reading the code, you will be shown the page encrypted in it.
How to decrypt a code using an Android smartphone?
Smartphones or tablets with any operating system can quickly decode different codes using the built-in camera. To do this, just install a special utility from the application store. They come in several types. More popular are programs for deciphering codes that import information from them into other applications.
Many applications have been released for Android smartphones that have the function of reading barcodes and QR. Almost all of them do their jobs well. You can download applications from Google Play Market. Here are examples of the best applications for deciphering codes.
BarCode Descriptor
This application has a simple interface and sleek design. A camera is used to read codes, which allows you to read them from any surface. Including advertisements and outdoor advertising.
The application allows you to open an encrypted link in the browser or immediately dial an encrypted phone number. An additional benefit is that the scan history is saved in the application's memory. It can be uploaded to social networks, SMS messages, or simply viewed as needed.
"QR and barcode scanner"
Another popular application allows you to scan any graphic codes. It features a more pleasant interface and more ways to interact with the information received.
The only drawback of the application is that codes cannot be downloaded as files or links. All other functions are the same as those found in the application described above. It is important that the code is in the center of the frame when scanning.
Barcode Scanner
Another application that allows you to read various graphic codes is Barcode Scanner. It allows you to open encrypted links and dial phone numbers. To read the codes, you need to point the camera at the image. In general, the utility does not differ in functionality from similar ones.
The only difference is that you can use it to generate your own codes. They can encrypt printed text, links and contact information. For advertising purposes, links to Internet resources are usually provided, but a link to download an application can also be encoded. Most often, developers do this by posting utilities in open areas and then writing explanatory texts for them.
Windows Phone app
The best application for reading codes for phones based on the Windows operating system is the usual Yandex search engine string. It can read any code, regardless of the plane of the image. At the same time, you do not need to press anywhere for reading to begin - you just need to point the camera at the code. Follow the link and use the information received only at the user's request.
After reading the information, you will see a screen with a snapshot of the code, and under it in small print the decrypted information will be indicated - a link, phone number or address. You can find out the details if you click on the line that appears. The application opens the website using the link, finds the address in Yandex Maps, and offers to dial a phone number or write a message to it.
There are also many other applications for phones running Windows OS, including analogues of utilities for other operating systems. But the main problems of the programs are long response times, lack of developer support, and errors during operation. For this reason, the utility built into the Yandex search bar is the best for equipment with this operating system. Moreover, it is Russified and understandable.
IOS app
Many applications have also been released for iOS equipment owners. The best of them is QR Reader. The developer is Tap Media. This application has the following features:
- auto-detection of the code - you need to hold down the photo key and point the lens at the code, the camera itself will focus on the two-dimensional image;
- Browser and map view are built into the interface;
- scan results can be shared via popular social networks or sent by email;
- checking sites for reliability before visiting;
- creating your own codes for distribution;
- ability to export scanned images to CSV.
The main advantage of this application is its speed. Moreover, the utility is distributed absolutely free of charge, and it is completely Russified. Additionally, it provides an option to select an application if the two-dimensional image does not hide text or a link. Problems arise only if a program that interacts with the required file extension is not installed on the smartphone or tablet.
Special applications for scanning QR codes from supermarket receipts
If you keep statistics of your food expenses or want to get cashback for purchases, you can use special applications. Now in all major chains you can see QR codes on receipts. They can also be read and a list of products can be uploaded to the application.
There are programs for consumers that help keep statistics and even make money on their purchases. One of the most popular applications is Edadil. It has one significant drawback - you will not be able to see what you bought and when. But for some goods you can get cashback, which can be withdrawn to your e-wallet or mobile phone balance. A list of products for the purchase of which funds are awarded can be seen in the promotions section. It is important that codes from receipts must be scanned within 24 hours after payment at the checkout.
Large retail chains also use QR code scanners on their websites and apps. They are used to receive additional bonuses. Another option is to use decoded information to participate in special promotions and sweepstakes from stores.
You can also scan codes from receipts in other applications designed to receive cashbacks:
- In Shopper,
- Qrooto,
- Together Cheaper.
They work with any stores, including online markets. These applications have many withdrawal options, and you can earn money on the maximum number of promotions from manufacturers. Rewards for one can vary from 5 to 300 rubles (depending on the terms of the promotion). Conditions for accrual of funds can be viewed on the promotion page. Experienced buyers recommend scanning codes from all receipts, since there are a lot of promotions and it is impossible to keep track of them all. You can receive cashbacks from several applications at once to make it as profitable as possible.
Most likely, you've dealt with QR codes before, even though you don't understand what they're talking about. But not everyone is so “unenlightened”, right? In modern realities, a person who uses smartphones has to adapt to technology and master it, otherwise there will be no further progress. Just look at the news that What’s App is popular not only among young people, but also among users who are well over 60. What can we say about some kind of QR codes, which are already found quite often.
QR technology allows you to store information in encrypted form, which is presented in a small square. Smartphones that can decrypt such data will follow the links encrypted in these tabs in one click. Actually, to make life easier for subscribers and customers, many services put up stickers, posters, banners with QR codes containing links to their official websites, instructions, postal addresses, and telephone numbers. Both fast and convenient.
QR technology appeared 20 years ago. Yes Yes! Only earlier it was used in the automotive industry by the Japanese, and in recent years it has been actively used in the IT industry, as it has found wide application, and, frankly speaking, it has “taken over” with its novelty.
Where are the codes mainly used? In fact, there are many areas of application! These could be online stores where QR is needed to quickly purchase goods and follow links. This also includes tickets purchased online. For example, you can purchase a movie ticket by paying with a bank card. Next, you take a photo of the QR code and in the cinema itself, the inspector uses a special device to scan the purchased ticket from your photo. Very comfortably!
Recently, this technology has been actively used in medicines, namely, on their packaging. After scanning, the user receives detailed information about the purpose, dosage regimens, etc. Another convenient area of application is utilities. Why enter multiple complex and lengthy invoices when you can pay with one click?
Actually, after all these examples, the question arises - how does QR code read on Android? What does the user need to do to read such a code in a store or subway? By default, your Android doesn't have this option (although it's surprising that Google hasn't thought of this yet), but you can download and install a specialized program to read them. And we have chosen for you the 5 most convenient and best applications for these purposes.
What programs are there?

Point the camera of your Android device at the code and the system itself scans it, and then displays information or follows a link that has been encrypted. As you can see, the whole process comes down to simple steps, so no special technical knowledge is required from you.
Login using QR code in Yandex
If you are not aware, you can protect your Yandex account by logging in via a QR code. You specify two-factor authentication in the settings in advance, download a special application to your smartphone and log in there. Now, in the future, to log into your account from a computer, just select the QR method on the main page, bring your phone with a camera and the system will automatically log in! In this case, you don’t even need to enter a login or password from your computer. Fantastic, isn't it? Only this has long been a reality...

It is also possible to enable automatic activation of the flashlight; it is activated when there is insufficient lighting in the room. The program will help you find information about the scanned product on the Internet, compare prices, etc.
