How to scan a qr code for a children's watch. Download the application via QR code. Is it possible to create a QR code yourself?

Each of us has at least once seen the characteristic black and white squares that flash on various products, on the street and even from TV screens. These icons are called QR codes (short for Quick Response) and carry certain information. It is worth noting that you can recognize the data encrypted in a barcode in a matter of seconds and from almost any mobile device, using certain QR recognition applications that scan codes. Moreover, you can create Quick Response yourself, using simple reader services. We will talk about how to use QR codes and recognize them using an Android device below.

QR Droid Code Scanner

We invite you to watch an introductory video that will tell you about QR codes:

QR codes – what are they?

QR code (Quick Response) or Barcode is one of the types of encryption, which is a kind of analogue of a barcode. Its main feature is that with a barcode scanner for Android, coding can be deciphered on literally any surface - on product packaging, subway walls, and even a TV screen. The invention was developed by the Japanese company Denso Wave in 1994, and is now used almost everywhere. Moreover, its scope of application is much wider than conventional marking. Most often, this encryption is used to denote the following formats:

• Personal Information. This type of encoding can be applied, for example, to a business card. This allows you to quickly save the desired contact by scanning the code and saving its recognized data in the device memory.
• SMS messages. Quick Response eliminates the need for typing. Using a special reader, you can see the finished message on the device display.
• Website or email address. A program for reading QR codes for Android devices will allow you to go directly to the site without having to enter characters in the address bar. Usually this is a site where you can find out everything you need about a product or service.
• Data about the geographical location of a particular object.
• Texts, poems and other information in Russian and other languages.

It is also worth downloading a barcode scanner because today such coding can be seen on almost every package of goods in the supermarket. Most often, manufacturers use encryption of the European standard EAN-8 and EAN-13. The number in the code name indicates how many characters are in the encryption. Thus, armed with a good smartphone or tablet with a QR scanner, you can read the information on the packaging - the history of the company, the composition of the product and even its price. Such barcodes are also applied to medicines. In this case they contain the central pharmaceutical number. You can decipher the recipient's address on letters and postcards, which allows you to automatically sort correspondence upon delivery.

How to download a barcode scanner program for Android?

To scan the code on your Android device, you only need a simple application that can be downloaded for free directly from Google Play. The operating algorithm of such a program is very simple - it uses the phone’s camera, captures an image, and then transmits the information to the screen. Moreover, with the help of many programs you can create Quick Response yourself, encrypting the necessary characters in them. There are a lot of such QR scanners for Android, and the most popular are QR Droid Code Scanner, ZXing Team and QR Droid.
Let's look at how you can download and install the Quick Response barcode reader on your Android device using the example of another well-known application, QR Barcode Scanner.
So, to find out how to scan QR codes on Android devices using the specified program, you need to:

1. Download the application on our website. Or go to the Google Play service, enter “QR code reader” in the search and select a reader from the proposed list, for example, Barcode Scanner. After the program is installed on your device, you need to go to the menu, select the application, download the QR scanner and open it.
2. Immediately after downloading and launching, the main menu of the program will open in front of us. In order to start scanning, you need to select the Scan Barcode item and point the camera at the Quick Response we need.
3. After the application finishes reading, information about the type of encryption will appear on the screen, as well as all the data that the scanned cipher contains. Thus, every user of Android gadgets will be able to easily read QRs on the street, in the subway, and on product packaging, without necessarily connecting to the Internet.

Is it possible to create a QR yourself?

Considering that matrix encryption is not licensed, anyone can create a Quick Response using simple applications or generators. In order to understand how these codes work and how you can create them, you need to find one of the services for generating matrix encryption that is freely available on the Internet.

On the site, you need to enter text data in a special field, which will be encrypted using matrix encoding. After that, just use the “Create Code” command and save the image in GIF, JPEG or PNG format of your choice. You can save the received code on your device, print it, or send it by email.

As you can see, the scope of application of matrix coding is quite wide. At the same time, every owner of even a simple Android smartphone can have access to the data encrypted in black squares. Simple QR code scanners for Android installed on your device will allow you to learn how to read QRs, recognize texts, addresses and geolocations, share them with friends and even create your own matrix encryption with data of almost any type.

After reading this article, you already know what these QR codes are and how to work with them. To consolidate practical knowledge, we suggest watching a training video on working with the QR Droid program.

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.

At the end of the 90s of the last century, Japan was captured by a wave of barcode fashion. The information encrypted in a regular bar was no longer enough - so its more advanced successor was born - a two-dimensional barcode or QR code. Its heyday came in the 2000s, when it was “sculpted” everywhere it was possible and impossible.
Now, of course, the fashion for this has subsided significantly, but, nevertheless, it is used often. But if there are no problems with scanning and recognizing the QR code on phones and tablets, then with computers and laptops everything is somewhat more complicated.

There are several ways to scan a QR code on your computer to read it. I will tell you about each of them, and you can choose the one that will be more convenient to use in your case.

1. QR code scanner online

Now you need to highlight the Curr with a frame with the mouse, and then release the button. Now the program itself will decrypt it, read it and give the result.

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.

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 string of the Yandex search engine. 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.
