"A concrete illustration of the U.S. side comes from the Customs and Border Protection (CBP) agency, which is seeking approval for its ESTA Mobile app—a visa‑free program that other countries could later adopt."
"The app would not only capture a traveler’s face and fingerprint but also request a massive amount of personal information, such as:
- Telephone numbers used in the last five years
- Email addresses from the past ten years
- IP addresses attached to uploaded photos
- Names, phone numbers, and dates of birth of family members
- Residential histories for both the traveler and their relatives
- Business telephone numbers and email accounts
- Full biometric data (fingerprints, facial scans, etc.)
"In total, CBP estimates that it will take roughly 22 minutes for each traveler to fill the questionaire."
