How to use a 2D barcode
This is movie poster with a 2D barcode. I took this picture with my iPhone as I walked out of a movie theater last week. The poster stood about 4 feet tall and looked like this:
The 'bar code' itself is about 24 inches square. I don't know why these are called 'bar codes' because they really don't have any bars at all.
I had heard about these codes that you could take a picture of with your mobile phone and then either using an app or a mobile website, convert them to online content. I had heard of coupons, advertisements, contact information etc. but I had never seen one in the wild. The idea here is that these codes can be posted on websites, billboards, T-Shirts, business cards. The possibilities are endless. People always say that this is the kind of thing that Koreans and the Japanese go wild over, but it was still new here and new to me. I wasn't sure what to do with it so I snapped 3 pics and went on my way.
When I got home I looked it up and downloaded the NeoReader app for iPhone. Since I already took the picture, I uploaded it to Flickr and then pointed my iPhone at the picture of a picture of a 2D bar code on my monitor ...and it worked, awesome.
Try it for yourself on the image above after you download the app for your iPhone (or other mobile device) It's a cool little surprise.
