The State Department announced this week that starting next October all U.S. passports will be implanted with computer chips. Sweeping new regulations say that passports issued after that time will have radio frequency ID chips that can transmit personal information including the name, nationality, sex, date of birth, place of birth and digitized photograph of the passport holder. Eventually, the government may add digitized data such as fingerprints or iris scans. Out of the more than 2,000 comments on the plan that were received by the State Department this year, more than 98 percent were negative.
