Summing up

As a result, we learned how to scan a QR code on Android in different ways. We hope this article was useful to you. If you still have questions, ask them in the comments. We will try to help everyone.

Even if this does not happen, some of the users on the site will definitely tell you how to get out of the situation and give good advice. You just have to bring it to life.

QR BARCODE SCANNER

  • There is a search bar at the top of the Google Play window. This is what we will use. We activate and write the name of our application. It is not necessary to enter it completely. As soon as the object indicated in the screenshot appears in the search results, just tap on it.
  • We will be redirected to the home page of the program. There is a large green button that says INSTALL. Click her.
  • We are waiting for the download of the application to finish. Since it “weighs” a little less than 5 MB, the process will not take much time.
  • Done. After the automatic installation is over, we can run the program right from here.
  • Also on the home screen (if activated in the settings) a launch shortcut will appear.

This completes the installation of the program, and we can proceed to the overview of working with it.

In the screenshot below, you can see the programming interface. Here it is divided into 3 main tabs. There is also a settings icon made in the form of a gear. The main tab “SCAN” contains 4 main tools:

  • Scan Barcode. This is the QR scanner that works through the camera;
  • Manual Key-in. Function of manual data entry about the code;
  • Decode from File. Decoding from a file. From here, you can open the previously downloaded QR code and read it;
  • Decode from Url. Scan by link.

At the bottom there are several buttons that do not carry useful functionality. You should not pay attention to them.

Let’s consider the program settings. There are quite a few of them here. Your screens will have screenshots of different configuration areas, but we will just voice some of the most interesting points.

For example, on the first screen, you can enable or disable the sound of the program. The same can be done with vibration feedback. You can set the operation mode when the program will start immediately from the scanner, bypassing the main menu. Another important feature is the automatic copying of data to the clipboard.

As soon as we want to start scanning and launch the scanner itself, the program will request access to the necessary system resources. Naturally, it needs to be resolved. Click the button marked in the screenshot.

Next, we aim the frame of the scanner so that the horizontal strip falls directly on the QR. Try to keep your hands from shaking while staying focused. Scanning will fail without normal sharpness.

Once the code is recognized, you will see the information given in the screenshot below.

There is a thumbnail of the tracked QR code, its format, data type and date. Naturally, in the window below we will see the content. In this case, this is a link to the manufacturer’s website. There are also 2 buttons “Go to Website” and “Share”. The first will open the official website, and the second will help. As a result, the site opened. Everything works well.

In addition to scanning QR, you can also create them here. To do this, go to the third tab. We marked it in the screenshot. All data types that can be encrypted are listed as a list. The following is supported:

  • phone book contact;
  • phone number;
  • Url;
  • Email;
  • attachment;
  • location;
  • any text;
  • bookmark;
  • calendar event.

It all looks like this:

When the data type is selected and set, we just have to click the “Encode” button. In this case, we have encrypted the link.

The output is this nice code. You can immediately share it or change the color.

Let’s try to encrypt arbitrary text as well. To do this, select the desired item.

Enter the phrase in the designated field and press the “Encode” button.

The result looks great. Let’s change its color again. We press the button intended for this.

Choosing the desired shade from the palette.

And admire the received QR.

Let’s move on to the next program, which also has impressive functionality.

How to scan QR code on Android with and without programs

A QR code is analogous to an older barcode. However, unlike him, he is more secure and practical. The barcode could only indicate some information, such as, for example, the website address. QR carries a lot more data and allows you to include anything you want. Thanks to all of the above, many programs have appeared on Android to scan such code. In this article, we’ll just talk about how this is done.

NeoReader QR Barcode Scanner

This program, like others, you can download and install via Google play or via a direct link. When this is done, you can go directly to work with her.

On the first launch, we need to satisfy the access request. Click “ALLOW”.

Next, we will be notified about the main features of working with the utility. To close the advertisement, click the button circled in the picture below.

Then a window with settings will appear. Here you will be able to choose a language, indicate your country, gender and age. The two checkboxes below allow you to enable or disable the program’s access to geodata.

You can actually start scanning. Point the camera at the QR code and NeoReader QR Barcode Scanner will automatically recognize its contents.

When the sign appears, we can either get additional information about it, or open it in a browser.

You can also choose exactly the browser you want.

And here is the result. The diaper pack was recognized flawlessly and we see the official website of Libero.

We think that these three programs will be enough for any person. Choose the most convenient for you and use at your discretion. We will talk about some of the features of Chinese devices.

Next, we can install the scanning engine. One of the proprietary algorithms is used: Zapper or ZXing. Below you will be able to enable or disable the crosshair, set up an automatic action after scanning, and enable displaying hints or copying a link to the clipboard.

In this section, you can set up sound, turn on and off vibration. The process of recording actions in the log and interaction with the Android Wear smartwatch is also configurable.

Then we can export or import a backup or set a date.

Allow the sending of anonymous data (it is better to disable it), activate the verification of the security link received during the scan, or configure batch scanning. Functions like zoom or highlight are available below.

  • Now let’s move on to the scanning itself. You just need to open the program and hover the central frame over the QR code. You don’t need to press anything. Just point your camera at a barcode or QR. The program works automatically and instantly recognizes everything. In my case, I pointed it directly at the QR code and “yandex.ru” was displayed for me. As I promised everything is very simple.
  • Practice yourself. Here is the QR code I created. If you see it on another phone or computer, then just point and scan. I will explain how to make my own QR code further.
  • Great, now let’s create our own. Go to the original menu and now select the “Generate” or “Generate” item. A line appears in which you need to write anything that you want to encrypt into a QR code. I entered our site. Click “Generate” or “Generate”.

    What is QR Code

    The history of the QR code begins in 1994 in Japan. By then, it had become clear that standard product information barcodes were no longer sufficient for industry needs. It was necessary to find a way to encode the data in a small graphical code that anyone could access. The solution was found by the developers of the Denso-Wave company.

    The QR code proposed by the company (from the English quick response) is a two-dimensional barcode, consisting of points that are recognized by the sensor, translated into binary numbers and converted according to a certain algorithm.

    A QR code is convenient because it allows you to encrypt several thousand characters in one picture. At the same time, the size of the QR code can vary greatly from a small centimeter square to a large image that can be placed on any flat surface.

    What else is your smartphone capable of?

    Nowadays, a person encounters such a form of interaction with the electronic environment as a QR code at every step. A page of a newspaper or magazine, a poster in a cinema, a plaque on an architectural monument. on all such media you can find a pattern of black and white squares in which useful information is encrypted.

And in the Chinese city of Hefei, elderly people are supplied with QR codes. If an elderly person gets lost on the streets, passers-by will find out his address through a QR code and help him return home.

    If you want to try several applications for reading QR codes, we recommend not to clog the device memory with them, but to install the programs on an external SD memory card. How to do this, read the article “How to install applications to a memory card”.
