A biometric passport, also called a digital passport or e-passport, is a passport that uses contactless smart card technology and biometric information to authenticate the holder’s identity.
Biometric passports contain an embedded electronic microprocessor chip and an antenna, usually embedded in the cover or center page. The chip contains both a digital passport photo and details on the passport holder, however, it does not contain fingerprint information.
Since August 2007, the United States has solely used biometric or electronic passports. The passport’s details are printed on the data page and stored in the chip, and public key infrastructure is used to authenticate the information.
