Extreme-range RFID tracking

Presented at Black Hat USA 2010, July 28, 2010, 11:15 a.m. (75 minutes)

If you think that RFID tags can only be read a few inches away from a reader you haven't met EPC Gen2, the tag that can be found in Enhanced Drivers Licenses - this 900MHz tag is readable from 30 feet with off-the-shelf equipment. Without amplifying the signal from a commercial reader we were able to equal the previous Defcon record of 69 feet, and with less than $1000 of equipment we acheived considerably further than that. This talk covers everything you'll need to know to read federally-issued RFID tags at extreme ranges and explores the consequences to personal privacy of being able to do so.
