Annalee Newitz and Jonathan Westhues demonstrated how easy it is to clone an implanted RFID chip at the HOPE number 6 Conference in New York last week. Newitz had a VeriChip RFID chip implanted in her arm and Westhues read the tag’s unique ID with a portable reader hooked up to his laptop, which recorded the ID. It’s easy to program a new tag with that unique ID, effectively cloning the original tag. See this Reuters article for more information.
