How many versions of e-passports are there?

The correct answer is that there are three versions of e-passports. E-passports, or electronic passports, are designed to be more secure than traditional passports and contain an embedded microchip that stores the passport holder's biometric data, making it easier to verify identity and enhance security at border control.

The three versions refer to the differing standards and functionalities adopted by various countries and international organizations. They include:

1. Basic E-passports: These contain a chip that stores the same information as the physical passport, with biometric data potentially included.

2. Enhanced Security E-passports: These not only contain additional biometric features but also have enhanced cryptographic protections to prevent tampering and address security concerns.

3. Mobile E-passports: This newer version incorporates technologies that allow users to interact with their passports through mobile devices, offering convenience for travelers who wish to manage their travel documents digitally.

Understanding these versions is crucial for recognizing the evolving landscape of travel documentation and security measures in international travel.
