Android for Dummies What is a QR Code?

In reviews of Android applications.MR (and on many other similarly themed websites) you might have noticed a black and white two-dimensional barcode picture like the one below. This is called a QR code. And that’s what we’ll talk about in this article.

Introduction

Firstly let’s remember what a barcode is, why it is needed and how exactly it appeared.

At first, several other marking options were tried, such as ultraviolet inked tags and others. But, for a variety of reasons, all of these ideas were not very viable. The idea for the barcode itself came to Joseph Woodland almost by accident. Sitting on the beach, he wrote a word in the sand, using Morse code, and then simply prolonged the dots and dashes downward, turning them into narrow and wide lines.

In 1951, Bernard Silver and Joseph Woodland showed their invention to IBM, but they felt that it would require too much sophisticated equipment to implement. At that time, it was really ahead of its time; laser scanners did not yet exist and reading barcodes was a challenge. In fact, Joseph and Silver’s idea was more than a decade ahead of its time.

The bar codes were not first demonstrated to the public until 1971 (when they were not straight lines but circles), and the first commercial barcode format (UPC or Universal Product Code) was developed in 1972.

Despite the fact that since then the formats of linear barcodes have repeatedly changed and improved, they still have one major drawback. a small amount of stored information. It was to overcome this drawback and were developed two-dimensional bar codes. In particular the QR code.

The QR code was developed by the Denso-Wave company in 1994 in Japan. Their fate is very similar to the fate of the linear barcode. the idea was interesting, but all was limited by the scanning methods. It is possible that it was used almost at once somewhere in production, but it became widely known among common people much later.

In Japan QR codes have become widespread in the early 2000s. By this time, they could be found almost anywhere: on advertising posters, product packaging, handbooks, business cards and many other places. But in the rest of the world the QR codes boom happened much later. approximately at the time when there appeared modern smartphones on Android and iOS, allowing easily and simply search, download and install additional programs. Including barcode scanners. According to the survey conducted in Russia in 2012 by J’sonPartners Consulting company, one third of respondents knew what QR codes are and how to use them. I suspect that now there are twice as many of these people.

The name “QR Code” itself is an officially registered trademark of Denso Wave Incorporated. Nevertheless its usage is free of charge both for individuals and legal entities and doesn’t fall under any licenses.

Reading QR codes

The main advantage of any barcode is the maximum ease of use. The QR code is not an exception to this rule. All what is required from a user is to click on the icon of the scanning program and to point the smartphone camera to the image of the code. The smartphone will do the rest.

On some smartphones the scanner software is initially installed. Owners of other devices can easily find and download similar programs on Google Play. I will cite the Barcode Scanner application as an example.

A screenshot of the main application window is shown below. As soon as you point your smartphone camera to the image of the code, it will be automatically scanned and decoded. In most cases, it will be a link to a site or an internet resource. For example, Google Play store. In order not to enter it manually, you can simply click on the button “Open Browser” in the left bottom corner of the application screen. Thus, after you have read the review of the application for Android.MR, you will be able to install it on your smartphone literally in one click, just by scanning the QR code from the monitor.

Creating QR codes

To create a QR code by yourself is not much more difficult. The easiest variant is to do it with the help of the same application Barcode Scanner. To do this, you need to click on the “Share” button, which is located at the top of the screen. And then either enter the text that you want to encrypt, or press “Application”, “Bookmark”, “Contact” or “Clipboard” button, so you can use the installed application, browser bookmark, contact from your phonebook or a pre-copied text.
