[nmarquardt] has put up an interesting instructable that covers building RFID tags. Most of them are constructed using adhesive copper tape on cardstock. The first version just has a cap and a low power LED to prove that the antenna is receiving power. The next iteration uses tilt switches so the tag is only active in certain orientations. The conclusion shows several different variations: different antenna lengths, conductive paint, light activated and more.

While in Vancouver, Canada for CanSecWest we had a chance to catch up with [Marc]. He showed off a very simple Denial-of-Service attack that works for most commercial RFID reader systems. He worked out this physical DoS with [Adam Laurie], whose RFID work we featured last year.
