hmmmm. this seems superfine, but i can’t imagine actually using one – sitting at the computer while reading the paper:
“When the Post and Courier newspaper in Charleston, South Carolina, went to press on Monday, it became the first printed paper to include hyperlinks in its stories.
These are not just printed URLs, but rather tiny barcodes embedded within news stories and advertisements. Readers scan the barcodes, which contain URLs, with a Post and Courier-provided laser pen attached to a PC with Internet access and they are taken directly to the specific websites.”
