I don't know specifically about biometric information, but I do agree that using additional identifiers makes a lot of sense. For example, if we mandated that the date of birth be used in addition to the name, we calculated that would reduce the number of false positives by a factor of 30,000, just based on the odds of two people having the same birthday. That simple addition to the system could reduce the number of false positives drastically, and then we could have redress for those few remaining individuals who still have trouble when they travel.
