Learn About QR Codes


What is a QR Code?

A QR Code (Quick Response Code) is a matrix barcode readable by QR scanners, mobile phones with a camera, and smartphones. The information encoded can be text, URL, or other data. The QR codes on this Web site will direct you to various resources from the Food Safety Research Information Office that are designed to be more easily displayed in mobile devices.

Getting Started:

  1. If you don't have a QR Code Reader already pre-installed on your mobile device, you can download one from the Android Market, Apple App Store, BlackBerry App World, or from any other source by typing "QR code reader" or "QR code scanner" and the model of your phone (iPhone, Android, Windows Mobile, Nokia, BlackBerry, or any other app-based phones with a camera) into your favorite search engine. Make sure the app is compatible with your mobile device. Most of these apps are free!
  2. Once installed on your device, launch the QR Code Reader from your list of apps.
  3. Point your phone's built-in camera at the QR Code. It works best if you try to cover as much of the viewfinder area as possible with the image.
  4. If the QR Code is successfully scanned, you'll be directed to additional information (text, photo, website or video). Just click on a link that appears on your mobile device to access the resource.
  5. You can try it out on the QR Code below to see if it works.
