Biometrics have been used
effectively in transportation applications for several years,
deployed for employee physical access and piloted for frequent
travelers. Programs such as INSPASS, which expedited passenger
movement through customs by means of hand-scan, proved
successful on a fairly limited scale. Similar deployments in
Israel have also proven successful, as have a number of pilots
using iris-scan technology in Europe.
However, the large-scale,
transactional verification applications where biometrics are
expected to be deployed over the next 12-24 months - border
crossing, trusted traveler identification, and immigration -
are much more complex and challenging than any biometric
deployment to date.
