A biometric passport is a type of passport that contains an embedded electronic chip. This chip stores the holder's personal information, including their name, date of birth, and a digital photograph. The photograph is usually a 3D image that helps to verify the identity of the passport holder. In addition to the photo, the chip may also store biometric data, such as fingerprints or iris scans. This technology enhances security and helps prevent identity theft, making it easier for border control agencies to verify the identity of travelers.
