The same strategy AFAIK works for UPC/EAN barcodes, for assigning IMEI numbers to cellphones, for book ISBNs. For an example description of the IMEI format check here: http://www.cellular.co.za/ieminumbers.htm (they refer to it as IEMI, don't ask me why). > They won't specify what *individuals* will get what tags, just that > it's a $2,500 Prada handbag -- which still raises the crime concern. Why would anyone *want* to invest $2k5 to a lousy handbag? There are LOTS of more useful things in that cost range. > Or you could use a multi-tier system like our current DNS setup. The > root RFID address-space servers will point queries to rfid.example.com... Could work neatly. It works for DNS, it works for eg. antispam blackholes, it works for many other purposes, it's reasonably fast. Could be implemented on existing DNS software in a single weekend.
