TidBITS article.
"For instance, you could take a photo of the 2D barcode on one of our articles using a special iPhone app as a way of getting the article's URL into your iPhone."
I've seen these used in Net-generated postage "stamps", pretty interesting.

Looks like the one used on Swiss railway tickets (if you buy one online and print out yourself).
These have been real popular in Japan for years. They stick them on signs and adverts all over. People walking by can snap a shot of it with their phone and then later use the URL encoded in the barcode to get more info from the web.
They are also used for official ids and other documents. There is a program out there that will back up your computer files as a huge 2d barcode on printed on paper. Paper lasts a long time and to recover the data you scan it and run it through the decider. Who'd of thought, eh? That hard drive of yours can be converted into stacks of paper to fill your room...
There's a number of interesting competing standards. See wikipedia for a table etc.

Seriously?! Shit, didn't see that coming. Interesting.
How many MB can it contain?
I hardly know where to start on this one. The camera in my Android phone works as a barcode scanner. I can scan one of these codes on a web page on my computer and the phone will ask me if I want to download some software.

And people are doing some very wild things with these codes. Bruce Sterling's Beyond the Beyond blog has videos about some of the uses of these things from time to time.

Here's a link to check out for "Paperback". With compression it says 3MB per A4 page at 600 dpi.
