RFID Shield in the Works

This is cool. Some people took an offhand comment from the world's leading RFID privacy expert, Katherine Albrecht, and is trying to make it a reality. Some Dutch researchers are working on a portable RFID shield. I wonder about their ability to actually block the RFID transmission of a target chip rather than just interfere with the transmission.

UPDATE:

I contacted the author of the RFID Guardian research to ask the following question:
Just one question. Does this actually prevent a tag from reporting to a reader or just give the reader fake data so that the reader can't tell which one actually came from the tag?
And her response:
The RFID Guardian actually jams tag responses from reaching the RFID reader.
