Biometric entry at the US Border has been fully operational for over a decade. However, the mandate for biometric exit remains unfulfilled.
The white paper "Closing the Loop: Completing Biometric US Entry-Exit"
from the International Biometrics + Identity Association (IBIA) offers a review of the mandate and a thorough analysis of concerns about cost, uncertainties about logistical implementation, and the erroneous belief that biographical data is sufficient to understand who is in the country.
HID Global is a proud member of the IBIA.
