Your smartphone has the ability to read both QR codes (which automatically take you to a website URL) as well as scaning 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. Here's where we show you how to scan QR and barcodes with your smartphone. See all smartphone tutorials and tips.
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.
How to scan QR Codes with an Android smartphone
This first thing you are going to need to do here is go to the Google Play store and download the free QR Code Reader app – the file size should be around 3MB depending on your smartphone.
Launch the app. From here it couldn't be easier, all you need to do now is point your smartphone's camera at the QR code you want to scan and the app will do the rest.
Note: if you want to use your Android's default web browser (for the results page) instead of the app's, then you simply have to uncheck this box in the app's setting menu. Take a look at our tutorial on how to get more storage on an Android device too.

Assuming you want to scan barcodes to find out information and/or a product's price comparison follow these steps.
