How to Scan a QR Code with Your Android Phone

How to Scan a QR Code with Your Android Phone on The Apps Depot Blog

We stumble upon little square pictures consisting of the different combinations of black-and-white points or large pixels all the time - everytime we hit the shops, basically. These days they are almost everywhere so let’s try to sort this mysterious stuff out.

QR: Definition and Usage

The Quick Response or QR Codes are the advanced versions of ordinary barcodes. They’ve gained a great popularity for several past years. The thing is the QR codes carry more information, using less space for this. Nowadays, one may find them almost everywhere. It’s just an incomplete list of their usage spheres: sharing contacts, storage data on loyalty programs, getting access to a network, reading the additional info about products, events, or other things.

Scanning a QR Code

QR codes can’t be read as an ordinary text and that’s why it should be decrypted first. To perform this operation, you’ll need only three components, and they are: a QR code placed somewhere, a phone with a camera module, and one of the QR code readers installed on it. There are lots of such applications in Play Store and almost all of them are free of charge.Actually, you may choose any of the most popular: QR Code Reader, Barcode Generator, ScanLife Barcode Reader, i-nigma Barcode Scanner, QR Droid, etc. As a rule, they are lightweight and don’t affect your device's battery life greatly.

All you need to do is to follow these simple steps:

  • Launch the scanning app.
  • Focus the camera on a QR code - usually, you don’t have to press any button.
  • View the hidden information - the Internet connection will be required if the content is stored online.

Moreover, most of QR scanning applications also offer an opportunity to generate your own QR codes for any purpose, if need to create them arises. It’s very easy and doesn’t take a lot of time.

    It works great for QR codes, but what about barcodes? Will these apps work both ways?
