A QR code looks like a picture of a maze or maybe a crossword puzzle, but it is actually a form of barcode which can contain a large amount of data. With the proliferation of smart phones that have cameras and are Internet capable, QR images are the way to easily and quickly connect the physical world to the information on the Internet.
A QR image can contain a web page URL, email address, phone number, text, or a combination of all of these. An image could contain all of your contact info that could be easily shared without having to type it all in. An image could contain event info, such as date, time, location, phone number and a web page link that could be added to your calendar with a single click of a button.
You are viewing a web page on your PC or laptop, but would like to view it on your smart phone.
