Your smartphone has the ability to read both QR codes (which automatically take you to a website URL) as well as scanning a barcode to bring up product information such as price comparisons and user reviews. All you need to do is download the right app and then simply point your smartphone camera at the codes.
First of all we should say that there are tons of apps out there that claim to do this, and a lot of them are very good. For the purpose of this tutorial we have chosen two popular apps that we are familiar with and we are installing both on an Android phone. You'll be able to find similar free apps for iPhone in the App Store.
