Fast access to more information–no more memorizing long URLs or searching for pens and scrap paper! Sounds good to an agency that puts a lot of website addresses on marketing material.
But is there a market in the Yukon for 2D barcodes? Would enough people know what they are? Do enough people have the right technology to use them?
My first thought when I heard about this technology was, "Aren't all barcodes 2D?" It took some explaining for me to understand what a 2D barcode can do and how it's different from the ones printed on everything from cereal boxes to underwear.
Technically, a 2D barcode stores information both vertically and horizontally, which explains why traditional barcodes are only one-dimensional: horizontal.
How do you use them?
step 1: You see it printed on a poster, in a flyer, on a box, etc.
step 2: You take a photo of it with your fancy mobile/blackberry/smart phone.
step 3: Your phone reads the barcode and connects you to the relevant information on a website.
This weekend I heard a radio program about early internet usage and it was interesting to learn that print advertising used to spell out in full "aitch-tee-tee-pee-colon-oblique-oblique" (http://). We hardly need to write “www” anymore! How did we get to a graphic instead of typed websites? When did we know it was okay to drop the “http” or the “www”? How does one help the public recognize a new technology without writing a multi-paragraph blog to explain it?
