The move to electronic passports is worldwide, driven by the realization that paper-based passports can be too easily altered and falsified. The large number of lost or stolen passports-more than 300,000 in the United States alone in recent years-meant there was a huge pool of paper-based passports potentially available to counterfeiters.
After the terrorist attacks on September 11, 2001, Congress legislated that all countries participating in the Visa Waiver Program-which lets foreigners visit without obtaining a Visa-must issue electronic passports. This led to international agreements and standards for epassports that are now in place.
Today, the United States and the 35 Visa Waiver Program countries are issuing epassports. Most other nations are in various stages of implementing a transition to epassports.
