[FOO] RFID and Bar Codes
The subtitle of this session is “Annotating the World”; someone is a good marketer.
Ross Stapleton-Gray is explaining how bar codes work, with an emphasis on the directory services they use. The RFID directories will be federated.
RFIDs have 96 bits, enough to tag particular cans of Coke, unlike bar codes that are the same for every can of Coke.
Marc Smith, a sociologist at Microsoft and the NetScan guy (data about newsgroups), shows a handheld reader that scans a bar code and pulls down info from the Amazon web server. Another button press and it does a google search. He contrasts this with the approach Ross outlined that relies on custom-built databases. “The swarm will build the database.”
AURA (Advanced User Resolution A-something), the Microsoft project, has a variety of “resolution services” that can be invoked to get more info. “We’ve just tightened the link between the virtual and the physical.” One example: if you want to know if there are any genetically altered foodstuffs in the can of peas you just bought, you can’t get that from the food label. But you probably can by looking it up in Google. Further, everything you scan AURA logs for you for your private perusal.
In the future, Marc says, a store might broadcast the availability of its resolution service. More interesting, he says, you might pick up an AFL-CIO resolution service that tells you that the pair of pants you’re looking at were manufactured in a sweat shop (“Would you like to see the QuickTime movie?”) and might offer you pants for a few dollars more that are “made by women who are allowed to urinate whenever they want to.”
Marc’s been demoing using a Pocket PC device but he says it’ll happen everywhere. Fr’instance, the code for visual deciphering barcodes is a mere 11K.

The “annotating the world” tag was Marc’s, and, yes, it was a good one. We also had Dave Mathews, the inventor of the CueCat scanner, though he didn’t much talk at this session.
I’d say that Marc and I addressed two complementary aspects of mapping codes to content: mine was in how the world will evolve to let “code owners” (e.g., a book’s publisher, or a can of soda’s manufacturer) describe their products and have that content found, while Marc addressed how third parties will offer up commentary, associating their content (“This soda sucks!” “This book rocks!” “This widget costs an acre of rainforest per hundred units!!”) with things, using the same underlying code schemes.
I think the two are closely coupled… there’ll be more interest in & incentive for third-party commentary when there’s a greater expectation that one can use codes as citations of “primary” information from manufacturers/publishers.
