Q: What are QR Codes? I see them everywhere!

A: QR is short for Quick Response. They have this name because a cell phone can read the code quickly. QR codes are used to take a piece of information from a transitory media and put it into your cell phone. Once it is in your cell phone, it may give you details about that business which allows users to search for nearby locations. It can even give you a coupon that you can use in a local store.

How to use QR codes:
First you need to make sure you have a QR code application downloaded on your smart phone. Then you take a picture of the QR code with your smart phone. Next, you will be redirected to a website using your cell phone’s web browser.

Why are they useful?
QR codes are more useful than a standard barcode because they can store and digitally present much more data, including URL links, geo coordinates and text. Another feature of QR codes are that they do not require a bulky hand-held scanner. You only need a smart phone that is able to scan the code.
