A recent article in Wired talked about a scientist initially assigning barcodes to moths. Below is a system to organize your shopping list. Barcodes are a quick and standardized way to categorize items, and combining this info with the Web offers many opportunities. What if I scanned the pens I bought at Staples and was given a web page listing the pen, their history (Wiki style), and then was shown prices for it in neighboring stores. The page can also show other similar products. Amazon.com meets Wikipedia meets a barcode scanner. There must be a quicker way to call up info about items I'm holding in my hand. Barcodes seem like an answer, in tandem with a tool like the one I describe above.
