What are QR Codes?

QR stands for Quick Response. It is a smarter version of the ubiquitous barcode, and was originally developed in Japan for the automotive industry. Machines can read QR codes faster than barcodes, and QR codes can store more data in less space.

If QR codes had stayed inside the factories, we probably wouldn't care, but now they are used for all kinds of things: coffee shop loyalty programs, e-tickets for sports and concerts, "find out more" links on classifieds or packaging, and share contact information.

For most of us, the main reason to use QR codes is to get a web link to find out more information about something or to get a password for a wireless network - scan the code and the information should appear in your web browser or connect to it. net. But how to scan a QR code? There are a couple of ways.

How to scan QR codes with an Android phone

There are several ways to scan QR codes on Android. On Pixel phones, you can do this without downloading third-party apps. The option is integrated directly into the default camera app. 

All you have to do is switch to Lens mode and point the camera at the QR code you want to scan. On Samsung smartphones, the Bixby Vision app can also be used as a QR code reader.

Google Lens

However, if your phone is neither a Pixel nor a Samsung, you don't have to worry - if you have the Google Assistant you should already have the Lens option. It can be found via the camera icon when the Assistant is in use. If it's not there, you can download the Google Lens app directly from the Play Store. 

It is one of best QR readers for android and it has some cool features like identifying plants and animals or information about nearby landmarks with AR overlay.

Of course, third party apps are always an option too and that's the application QR scanner which we recommend more:

QR Code Reader

QR Code Reader is one of ours favorite apps for scanning QR codes- It's simple and free, works fast, and doesn't show you ads (unlike many competing apps).

It is compatible with almost all Android devices and versions - if you have Android 2.3.3 or later, you are good to go, provided, of course, that your device has a camera. If the code you are scanning is designed to take you to a website, you will also need a data signal or a wireless connection.

To scan a QR code, all you need to do is load the app, start the scan, and point the camera at the QR code. 

Line it up inside the guide arrows and that's it: QR Code Reader recognizes it and provides the appropriate information, performs the appropriate activity or, in the case of phone numbers and other contact information, asks you what actions to take. 

It also records the history of your scans so you can look back at the codes you pointed your phone at.

It has the same basic functionality as the QR code reader, but adds support for scanning all popular barcode types (UPC, EAN and ISBN) to show prices, reviews and anything else related to the products you scan (although a reasonably good camera is required for barcode scanning).

How to create my QR codes?

Yup! There are piles and piles of coding apps for Android, although during reviews it seems they all have flaws. It's probably easier to go to the Scan developer website, where you can create QR codes for social media, Wi-Fi access, contact information, and many other types of data for free in your web browser.

Are there any risks involved in scanning QR codes?

Currently yes. A scam known as “attagging” involves pasting new QR codes over existing ones, for example by pasting a QR code label onto a poster. 

The new code could link to malicious software that could then access your camera or personal data. 

In Russia, a QR code scam caused phones to send messages at a premium of € 6 per message. Such malware is very, very unusual, but it exists.
