jdray's Journal: IBM creates "Clipped" RFID tags

IBM and Marnlen RFiD are collaborating on an RFID tag format called a "Clipped Tag." From the article,

"Clipped Tag technology allows consumers to tear off a section of the tag which in turn reduces the tag's read range to just a few inches, protecting consumer privacy while maintaining the benefits of the technology, such as product authentication or recalls.

I wonder why they don't just break the loop of the antenna. If someone needs to read the tag at a later date, a couple of contacts, left bare, could reconnect the loop and make the tag readable again.
