There is no need to explain for a long time “what a barcode is”, because it is on almost every product and serves to obtain various information about it. It is not necessary to buy separate laser scanners that connect to computers, since there is a simple and possibly unusual solution in the form of a camera on any smartphone.
Many large stores provide the opportunity to view product information in this way. In addition, there are independent ratings in which you can also scan a barcode to quickly go to the product review page. The most common services and application scenarios are discussed in this text.
How to find out if your phone has a QR scanning app
Most mobile devices have a built-in application for reading the quar code. To find out if your mobile phone has this, you need to go to settings and select the section with all applications installed on your device.
In the main menu you need to find this section and go to the list of programs. Among them, find an application with the word QR in the name or the Yandex application. In some cases, the scanning application is available through the camera interface on the smartphone.
If you can’t find the application in the specified places, try opening the additional menu at the top of the screen (curtain).
It contains quick links to phone system utilities and popular functions. To turn on the scanner, you need to activate the button from the menu and configure the scanning lens. There are also third-party code readers with more functionality and capabilities.
Additional details and recommendations
Developers from Yandex recommend using one-time passwords instead of permanent ones, which come in the form of SMS and help confirm payments, transfers and interaction with various services and financial products.
One-time passwords have many advantages. Firstly, you don’t need to remember a complex combination made up of 6-10 characters, which is easy to get confused due to numbers, symbols and letters. Secondly, the level of reliability increases significantly. Fraudsters will not even have time to get close to the authorization menu before the one-time password loses its validity and will no longer be used to make transactions. Thirdly, situations will no longer arise when it is impossible to remember, change or find confidential information, because a special newsletter will take care of everything.
To activate one-time passwords, go to the settings page (https://money.yandex.ru/strongsec/), attach your mobile phone number and select the “Passwords in SMS” option. When using mobile software developed for iOS (https://itunes.apple.com/ru/developer/yandex-llc/id308094652) and Android (https://play.google.com/store/apps/details?id =ru.yandex.money&hl=ru), there is an option to receive combinations in the application. From now on you can withdraw Yandex Money, make payments or make payments in two invoices.
The Yandex payment password is not a cure for all ills, but it is a sure way to secure online purchases and reduce the risk of losing money due to the actions of scammers.
How to scan a QR code on your smartphone screen
The scanner on the phone can determine information on the code, which is located on external sources: on the display case, packaging, goods, etc. It works through the front camera and can display encoded information on the phone screen. Not all scanners have the ability to detect barcodes on the phone screen itself. There are two ways to scan it: using another application or an online scanner. Choose the method that is more convenient for you.
This QR Scanner for Android opens this opportunity on users' smartphones. It has a “Scan from Gallery” function. Open a viewing image that is saved in memory and start scanning in the program.
If the picture is located on the smartphone screen online, for example, on a website that you visited through a browser, take a screenshot of the screen. The photo will automatically be placed in the gallery, from where you can work with it through the downloaded application.
The QR Scanner application works with different types of codes, can detect barcodes, and opens links and contacts encoded in encrypted information. Provides a set of functions for working with decoded data.

Collecting statistics from budget forecasts
The program supports the collection of statistics from the “Budget Forecast” section.
The table records the predicted values of frequencies, cost of clicks, CTR, budgets for all types of traffic volumes at once, taking into account the user’s regional settings, periods, currency, etc.
When batch processing phrases, anomalous statistical values are sometimes observed on the service side. It has been noticed that when non-standard collection periods are used, anomalies are more common.
To switch between modes based on traffic volume, click on any cell of the Yandex.Direct columns (1) and select mode (2) in the system contextual tab.
The task can be launched in two modes: in the Yandex.Direct statistics collection mode or in the Yandex.Wordstat frequency collection mode.
In both modes, all available and supported statistics are collected from the service response page, however, the modes determine the purpose of the collection, which is taken into account when forming a parsing queue when the process starts (in the uncollected mode).
Yandex.Direct statistics collection mode
When you start collection in this mode (in the mode for uncollected ones), phrases with missing statistics in the Yandex.Direct columns will be added to the queue.
The service supports standard search operators, . Depending on your goals, you can specify the query type: word, “word” or “!word”.
Unfortunately, the word order fixing operator ` ` is not supported here (the service ignores it and cuts it out of requests).
Optionally, you can enable integration of negative keywords.
The service has a number of requirements for negative keywords regarding their number and length. The program does not perform a preliminary check of the validity of the list of negative keywords, so to avoid errors, use only valid negative lists.
Yandex.Wordstat frequency collection mode
Yandex.Direct and Yandex.Wordstat have a lot in common: both services display the number of impressions of a phrase (one of the key metrics when researching phrases) and support search operators.
This allows you to quickly receive data on impressions (frequencies) in batch mode. The program can perform such queries and record statistics directly into Yandex.Wordstat columns if you set the collection goal to collect Yandex.Wordstat frequencies.
When you start collection in this mode (in the mode for uncollected ones), phrases with missing statistics in the Yandex.Wordstat columns will be queued.
Collecting frequencies through a budget forecast allows you to reduce the time for collecting frequencies by up to 30-50 times.
When batch processing phrases, anomalous statistical values are sometimes observed on the service side. It is noted that when using non-standard collection periods, anomalies occur more often (for example, the annual frequency can be 0, and per month - 150; or the phrase frequency can exceed the base one; etc. ).
After selecting the frequency collection mode (1), specify the types of frequencies: word, “word” or “!word” (2).
You can select several types at once, but at least one of them must match the mode selected in the “Forecast request format” column.
This is because queries are executed specifically in the budget forecast tool. And together with filling in the frequencies in the Yandex.Wordstat columns, the program will also record “side” Yandex.Direct statistics.
If you set the settings using the example above, the program will first receive data for a broad match (word), write frequencies to the project, and ignore Yandex.Direct statistics, because The occurrence type does not match the one selected in the Forecast Query Format field.
Then the phrasal occurrence (“word”) will be processed similarly.
Finally, the exact phrasal occurrence (“!word”) will be processed, etc. this time the mode coincides with the selected priority for the forecast, then statistics for Yandex.Direct columns will also be recorded in the project.
How to scan a QR code online
A less troublesome way is to scan in real time on the website https://dewiar.com/xscan. On the main page, select one of the scanners. To use it you need to use a laptop.
Laptop computers have built-in web cameras, which will help the site “see” the image on the screen of your smartphone with a QR code. Or use a desktop computer with a camera connected. Then activate the web application and bring the image to the webcam.
Encrypted information will appear on the computer screen, which can be used further for its intended purpose. If a web address is encrypted in the code, the application will prompt you to follow a link or show text and digital data from the code. The site can be useful not only for deciphering information on QR codes and barcodes from a smartphone screen, but can also create codes. The button to create is located on the main page at the bottom.
There is a paid version for using the decryptor on an ongoing basis. A paid account provides the user with additional opportunities.
Method 1. Smartphone with a built-in scanner
The gadget market is so oversaturated that every manufacturer is trying to provide their child with something special. Thus, a number of models have a QR code scanner, and information can be read online from the phone’s camera without installing additional tools. These include the following smartphones:
- iPhone with iOS above 11.
- Samsung and its Bixpy application, available on Galaxy S9/S9+/Note8/S8/S8+/A7 2018/A5 2018/J7+ and W2018 (China) - information from the official website https://www.samsung.com/ru/apps/ bixby/vision/
- HuaweiHonor.
- BlackBerry with business card scanner.
A QR code allows you to read information online through your phone (smartphone) camera. Regardless of the operating system, each owner of the built-in scanner function must do the following:
For iPhone:
- “Camera” → “Settings”.
- Drag the slider as in the screenshot.
For Samsung:
- Launch "BixpyVisiong".
- In the upper right part, select “Settings” - the gear sign.
- Drag the slider as in the screenshot.
- At the bottom, select "QR Code".
For BlackBerry:
- Launch the camera → select “Mode” → “Scanner”.
Simply point the camera at the desired image and the information will be read.
This is how we easily answered the question of how to scan a QR code online on a mobile phone camera.
What is a QR code?
A QR code is a mark made of dots and lines that can be decoded by a special application. In Russia, this type of information encoding is just beginning to become popular, while in Japan, where it was invented, QR can be found at every step.
Codes are very popular; they are used for business cards, invitations, and even used in correspondence. This seemingly small area of the image can contain a lot of information.
- QR can encode 7089 digits in different orders;
- Text in English, numbers, combinations of this data - 4296 characters;
- And 2953 Cyrillic characters.
Often, product manufacturers use this type of code to place additional information on the packaging. For example, a website for ordering products in bulk, operating instructions, and other information.
After all, if you placed a description of the product and its instructions on the packaging, you would have to use up all the space. But one small code can open a web page with important information on your phone. Public establishments encode information important for their establishment into QR. This could be a WiFi password, promotional codes and promotional data.
In China, using a code, visitors to cafes and restaurants can pay bills or leave tips. There are services that generate codes. Users can create QRs themselves and encode any of their information into them
Yandex two-factor authentication for other services
For Yandex.Mail, Ya.Disk and other Yandex services, it is possible to create different passwords. This will significantly increase the level of security of personal data and the account as a whole. You can read about their safe storage.
To do this, go again to the Passport - Access Control
. Select the program, in this case - Disk Access
.
For convenience, we call this connection, for example, My disk
and click Create password
.
So, the password has been created, and it will only be displayed once. Therefore, if it is not saved, then it is better to delete it in the future and create it again.
Now you can connect to a Yandex network drive. Through any file manager we gain access to Yandex.Disk using this password.
Thus, Yandex.Disk and the main Yandex account will be protected with separate passwords using the two-factor authentication function.
Online QR code generator
The site https://qrcoder.ru makes it possible to generate a QR code from information that the user wishes to encode.
In it you can create plain text, add a link to a website, create an SMS message or a business card. Quick links to creating such codes are located in the block for entering information on the site. The user will be able to select the appropriate QR code size. And after creation, copy the link to the code or paste the HTML code into the web page of your blog or social networks.
- Enter the code in the main field, add the necessary digital information;
- Select a size from 1 to 6 under the form;
- Click the "Generate Code" button or on the keyboard Ctrl + Enter.
Get the QR link or copy the embed code. The image can be saved to your phone's gallery or to a folder on your computer. To do this, you need to right-click on the code field and select “Save image” in any browser.
The creators of the site are developers of mobile applications for reading or creating QR. The link to their products is in the top menu of the site.
Is it possible to restore Yandex wallet after deletion?
What to do if the YaD wallet is hacked by scammers and deleted by them? If this happened not so long ago, then you can write to the technical service of the service and ask to restore the payment resource, citing a valid reason - hacking by unauthorized persons. To do this, you will need to provide the operator with certain information:
- answer to a secret question;
- login and code password;
- wallet number;
- phone number;
- initials and other personal information.
After more than 3 months have passed since the profile was hacked, it is no longer possible to do anything. All that remains is to register again.
To avoid any difficulties while using Yandex Wallet, especially if you lose access, it is recommended to fill in as much information as possible in the registration form. In the future, this will help in restoring your personal account.
Scan settings in the application
Most QR scanners have the same settings, since their purposes are the same. Some Chinese smartphone models do not have separate scanning applications. They're built into the Camera apps. Before looking for a third-party program to deactivate QR, try turning on the camera on your smartphone and pointing it at the code to check. If you still don’t have a scanning function on your phone, download the application from Google Play by request in the search bar.
In the program settings, the user will be able to enable history and view all codes that were scanned previously. Enable automatic creation of duplicate codes, and they will be saved in the phone's memory in a separate folder. It is also recommended to turn off the function for automatically opening web addresses on the Internet. The QR may contain a virus site encoded that can harm personal information on the device. Or download a spy program to your phone that tracks your actions in real time.
Each scanner works with audio by default. They can be turned off along with the vibration response, which is activated when the picture is decrypted. Before downloading a new application, familiarize yourself with its features. And download the program whose functions suit your tasks.
Permanent payment password
That is, this is a combination of numbers that a person enters every time he makes a payment from an electronic wallet. This is something like a PIN code, only for remote transactions.
On the one hand, this is convenient, but with security everything is bad. If scammers find out this permanent code, and there are plenty of methods for this, they will take all your money. There is no expiration date of a few minutes, so they will have time to commit the theft.
What Yandex advises users of permanent passwords:
- change the combination regularly, at least once every six months;
- do not use this password on other people's devices;
- Do not under any circumstances enter the code when performing a transaction through free WI-FI zones;
- Do not remember this code in the browser; it is much safer to enter it manually each time.
Frequency collection
Collecting frequencies allows you to assess the popularity of queries.
The service displays the number of impressions of a request over the last 30 days.
Statistics are not updated daily, so do not take this period literally.
The service supports various search operators, so the program is able to receive several types of frequencies.
The program automatically adds the necessary operators when collecting a particular type of frequency (there is no need to manually add operators to the text of requests).
Base frequency
The base frequency corresponds to the broad type of occurrence of words. To execute a request, it is enough to send the request itself in its original form:
- fresh bread
- conditional probability
- Bayes' theorem
The results may also include other phrases that are indirectly related to the request “fresh bread” in broad terms: buy fresh bread, fresh rye bread, bread recipe, fresh pastries, etc.
Phrase frequency
Phrase frequency records the composition of words in the search query, and impressions are counted for the entire phrase. To execute the query you need to add double quotes:
- "fresh bread"
- "Bayes' theorem"
- "distribution density"
In the results for the query “fresh bread”, only phrases with the same set of words will be taken into account: fresh bread, fresh bread, etc.
Accurate Phrase Frequency
The exact phrase frequency records not only the composition, but also the word forms of words in the searched query. To execute the query, you must add the operator ! before each word in the query and put it in double quotes:
- "!fresh !bread"
- "!Bayes' theorem"
- "!density !distribution"
In the results for the query “!fresh bread!” Only phrases with the same set of words in the same word form will be taken into account: fresh bread, fresh bread (the order is not fixed).
Exact phrasal frequency with order
The exact phrase frequency with order records the composition, word forms and order of words in the searched query. To execute the query, you must add the operator ! Before each word in the query, put it in and double quotes:
- "!fresh !bread"
- "!Bayes' theorem"
- "!density !distribution"
In the results for the query “!fresh bread!” Only phrases with the same set of words in the same word form and in the same order will be taken into account: fresh bread.
Frequency by mask
You can independently define the request mask using the operators supported by the service.
The request mask must contain a QUERY fragment, which, when collecting frequencies, will be replaced with the text of the request under study.
Recovery options
There are three ways to recover a forgotten payment password. Let's look at each of them in detail.
Via SMS
To perform a restore via a mobile device, follow these steps:
- Go to the official resource of the Yandex system. Money and log in to your account.
- Left-click on the “Payment code recovery” menu. There is such a link on every page where a password is required.
- Go to the “If a phone is linked to the wallet” tab and click on “Remember password”.
- The system will redirect you to a page where you will see the inscription “Receive SMS”. This button will be one on the page, so it is difficult to miss. Since authorization is successful, the Yandex service will automatically calculate the mobile phone number associated with the account. Now you need to wait until the message arrives on the gadget.
- Enter the received one-time password in the “SMS code” field that will appear after clicking the button. Confirm the action.
- A window will open where the user must enter a new password and email address to receive notifications. Enter the data and confirm the action. If during the task you change your mind and decide not to restore the code, you can refuse by clicking the appropriate button.
The channel “Promotion of MLM on the Internet - Irina Klepikova” published a video that shows the procedure for restoring a payment code.
Using a recovery code
To restore data, you can use the special code that you specified when opening the wallet:
- Log in to the Yandex system. Money.
- Go to the payment code recovery section.
- Find the “Send email” menu and click on it. A window will open with your email address written in it. The system will automatically send a message to this mailbox with instructions and a link to the information recovery page. An email from the Yandex system is sometimes recognized by mail servers as spam and ends up in the appropriate folder. If the message does not arrive, check your Spam folder. If there is no letter in it, make sure that your email is correct in your profile.
- Click on the received link. On this page you need to enter a recovery code. This is given no more than five attempts. After the fifth password entered incorrectly, the system will automatically block the cash account.
1. Log into your account and go to the code recovery menu.
2. Click on the “Send email” button and follow the instructions.
By writing a statement
If it was not possible to recover data using the two methods described above, you can send a message to the technical support service, to the system security department. This is done if access to email and the linked phone is lost or the data was entered incorrectly.
To contact the security service, go to the section “Help” - “Passwords” - “Permanent payment password” and enter information about yourself there. Print and sign.
There are two ways to submit a request to technical support:
- Having personally visited one of the Yandex offices. They are listed on the official website in the “Contacts” section.
- By sending the document by mail to the address: Moscow, 119021, PO Box 57, Yandex LLC. Money. In this case, you will need to attach copies of the main page of the passport and the registration page. One of the documents must be notarized: either a copy of the passport or a signature on the application.
Processing your request may take up to several weeks. After this time, the phone number specified in the application will be linked to your account. The gadget will receive an SMS with a one-time special code. Enter it on the site. The old payment password will be reset and you will be able to change it.
Where is the best place to use it?
Of course, some users may object, arguing that two-factor authentication is too much “unnecessary steps”, and in general, it is intended for paranoid people who always think that someone is watching them.
Perhaps they are right in some ways. For example, for social networks it is not at all necessary to use this method of protection. Although here one can argue. As a rule, attackers try to hack the accounts of administrators of popular “publics.” And you, most likely, would also not want to one day notice that your account in one of the “social networks” was hacked and completely indecent photos were posted on the “Wall”.
As for other services, for example, Yandex two-factor authentication will allow you to safely store your registration data from WebMoney and others) or letters containing secret information.
Restoring access to your account with 2FA
If your device breaks or is lost, you can regain access to your account with 2FA. To do this, you will need a PIN code from Yandex.Key and access to a phone number. Therefore, if your smartphone has been lost, first of all you need to block the SIM card and restore the number.
- On the recovery page, enter the requested data and click “Next”.
We indicate the phone number associated with the account with 2FA and click “Get code.”
Enter the numbers sent and click “Confirm”.
The system will prompt you to enter the PIN code from the Yandex.Key application.
We come up with a new password, check the box to sign out from all devices, and confirm the actions.
Access to your account has been restored, but two-factor authentication will have to be set up again. To do this, click “Enable” and repeat the steps described above.
If you do not remember your login, you can still restore access by phone number.
If you have forgotten your PIN code or phone number, you will not be able to restore access this way. In this case, you will have to write to support and then use their recommendations.
