What is a QR code: Practical uses explained
A QR or Quick Response code is a two-dimensional bar code that you can scan to access a website, an application, or other media. It’s like scanning a bar code in a supermarket, but better.
The fun bit is that you can generate a QR code yourself. Below is a QR code generated using a free online QR Code generator. Scanning it will take you to the Sony support website.
How to scan a QR code on your smartphone?
In modern smartphones, scanning a QR code is easy. Follow these steps:

I can't scan a QR code with my smartphone. What should I do?
If your smartphone doesn’t have a built-in QR code reader (Android 7 and lower), download a QR code reader app. Free apps can be downloaded from the Google Play Store.
Here are some tips on how you should scan QR codes with your smartphone:
- Hold your smartphone about a foot away from the QR code when scanning.
- Slowly move your smartphone towards the QR code.
- Make sure the QR code is clearly visible on your device's screen.
- Don’t scan at an angle.
- Don’t shake your device when scanning.
- Place the QR code on a plain background without patterns.
- Scan QR codes in bright lighting conditions.
- Make sure your shadow is not covering the QR code.
- Clean your smartphone’s camera lens.
Your device will either scan the code automatically once your camera is focused, or you will have to press a button in your QR code reader application. Keep in mind that scanning and processing QR codes can take a few seconds.
