Types of codes and capabilities of the “QR Code Reader PRO”

What is a barcode and why is it needed?

The barcode hides information about its type and place of manufacture of the product. A rough analysis of numbers encoded in the form of strips of different widths will not provide much information: the barcode database will provide most of it. It differs for each store depending on the assortment presented for sale. This will become known: price, name, product photos and other characteristics that are known to the store.

It is not necessary that the code be presented as black lines enclosed in a rectangle on a white background. You can simply indicate it in numbers. Some manufacturers take a smart approach to the design of entire packages, which is why barcodes are sometimes presented in various interesting shapes and colors. Still don't know how to scan a barcode on Android? Read our material to the end, where we described all possible methods.

How does a barcode differ from a QR code?

A QR code allows you to encode any information that can be displayed back on any device. Barcodes require connection to a database (that is, the use of special applications for each store) to obtain detailed data.

To make it easier to remember:

QR code – equilateral, with large squares at the corners;
barcode – striped, often (but not always) located in a rectangle.

Barcodes in stores usually indicate combinations of numbers. Despite the ability to encode other characters, it is not widely used. There are different coding standards, but the average user has no use for them - this information is important mainly for manufacturers.

Codes starting with the number "2" are unique to each store. This means that the selling company can label products this way at their own discretion, if the manufacturer has not applied the sticker themselves (the most striking example is fruit in supermarkets).

QR codes have already been discussed on the site in the text “How to scan a QR code on an iPhone.” There is also an article relevant for Android.

Codes that the application scans

Scope of the code

QR code (Quick Response) can be translated into Russian as “quick response”. It is a database similar to a barcode. The main difference between them is the way the information is encoded. If a bar code uses stripes for this, then a QR code uses squares. Using special software, you can encrypt absolutely any information.

For example, an organization can encode the address of its Internet page in this way, and then place the finished code on the product packaging.

As a result, the user will be able to scan it using a QR code reader for Android and quickly go to the web resource. This is much more convenient than typing all the necessary characters into the browser yourself.

Program features

What is it, why is it needed?

Not everyone pays attention to this, but there are tons of QR codes around us. They are on almost every advertising brochure and billboard, on promotional leaflets in cafes and restaurants, on tickets for concerts, theaters, etc. Behind each such graphic key can hide important, useful and simply interesting information. Let's look at the types of software products that help in decrypting them.

This is software that makes it possible to read printed graphic elements from packages. It may contain interesting information about the composition, manufacturer, price, etc. In any supermarket, you might have noticed how the cashier uses a special device at the checkout to punch through goods.

QR barcode scanner for Android

Passwords and settings for connecting to a specific Wi-Fi network.
Various types of promotional materials.
Some products are marked with special marks that confirm their originality. This allows you to distinguish expensive branded products from cheap counterfeits.

The scope of application is not limited to these options. They are increasingly used as business cards, carrying a fairly large amount of information. The function of automatically recording a number in the contact book is especially convenient. If desired, you can diversify the functionality with various specific options.

People in China use a QR code scanning app for Android to pay. After selecting purchases at the checkout, a unique combination is formed for a specific client. Having counted it, a person automatically confirms the debiting of a certain amount of money from his account.

In other countries, technology is not yet so actively involved in this area. But progress does not stand still, and the system develops day after day, capturing more and more new areas of human life. In the near future we can expect the introduction of this convenient method of information exchange in many business niches, as well as at the household level.

Actions with a scanned image

Built-in scanner in your phone

With the growing popularity of graphic keys, more and more manufacturers are adding a QR code scanner for Android to their device. In this way, a person gets the opportunity to scan the necessary image without installing additional applications. A useful function is provided in Samsung, Huawei, Horor and other models with the new OS 9.0. To obtain accurate information about this option, just look at the characteristics of the device or the seller.

Reading a QR code for Android occurs according to a simple algorithm, which is identical in all cases. The user enters the program, points the camera at the image and waits for the image to be processed. Then the following steps occur:

image transmission;
recognition of different parts of the picture (white and black);
determining the code version;
receiving and reading information, correcting errors;
getting the data header and using the mask;
reformatting graphic elements into binary code;
reading the received code and creating a sequence of characters from letters and numbers;
displaying information on the display.

In other words, a QR code is a group of binary information that can be scanned using a phone or other device. The main thing is that the application contains the necessary algorithms.

There are two ways to scan a QR code on Android phones. Let's briefly look at their features:

Through Google Assistance. The most convenient way to scan a pattern is to use a special assistant, which is found in all smartphones with the new Android system. Depending on the smartphone, it can be called up by long pressing the Home button or directly through the camera. In the latter case, you need to log into the device, click on the special icon and select the QR code. After this, point the camera at the picture of interest and wait for recognition.
Using software. Some devices already have a special application for reading QR codes for Android installed. In this case, you need to go into the program and follow the standard algorithm - place the picture in a special field and scan it.
Through the camera. Some are able to scan a QR code online on an Android camera. When entering this section, the user can select an item of interest and recognize what is hidden behind a particular graphic key. For example, this option is provided in Meizu M5. To carry out the work, enter the Camera application, click on the Scanner icon and point the camera at the image. The phone should scan the code and issue an encrypted link. Additionally, the following actions are available: open in the browser, copy and transfer.

Today you can read QR codes for Android on all modern phones with the new OS. In most cases, this option is available through Google Assistance, but in some models other options are possible.
