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?The RFID Guardian actually jams tag responses from reaching the RFID reader.
