If your U.S. passport was issued after June 2007, you have an electronic passport. If it was issued in the 12 months prior, it is likely you have an epassport. The way to know for sure is to look for this logo imprinted in gold on the cover of epassports. The electronic security features inside are designed to prevent anyone but you from successfully using that passport. If stolen, your passport picture could be replaced by a fraudulent one on the printed data page, but the digital copy of your picture on the chip can’t be changed without detection.
