U.S. TO IMPLANT ID TAGS IN PASSPORTS
The U.S. State Department plans to implant electronic ID chips in
U.S. passports to allow computer face-recognition systems to match
facial characteristics of the digital passport photo on the chip
against a photo taken at the passport control station and against
photos on government watch lists. The change is planned despite
warnings that face-recognition technology has a high error rate.
Critics suggest using fingerprint identification instead, as a more
reliable technology. The new passports are scheduled to enter use in
2005.
