About QR codes

Explain by Google and taken directly from on Google/Mobile Help

What’s this black-and-white graphic?

You’re looking at a type of barcode called a QR code. It’s designed to squeeze bits of information down into a square that mobile devices can scan quickly. Once scanned, a QR code gets translated into usable information, for example, a link to a website that you can go to right away, without typing anything. How convenient!




How to use to scan a QR code, your mobile device needs:

1. a working camera
2. a barcode scanner app that can read QR codes

There are many apps that can scan QR codes, and availability of a particular app depends on your device.

• Android devices
  • We recommend using the free Barcode Scanner app or Google Goggles. Just open Google Play and search for ‘barcode scanner’ or ‘google goggles’ to download.
• Apple devices
  • We recommend using the free QuickMark app or Google Goggles via Google Mobile App.
• Other devices
  • We recommend searching for ‘QR reader’ in your app marketplace — if your device has one — or searching for the model of your device and [qr reader] on Google.

Once you have the appropriate barcode scanner app installed on your device, just open the app, point your camera at a QR code, and scan.

Go ahead and give it a try on the QR code above!
