The Federal Aviation Administration has proposed that all pilot certificates include a photo of the licensee, but one lawmaker wants to know why the passport-size cards will not include biometric identification five years after Congress passed a law requiring such unique identifiers.Rep. John Mica, (R-Fla) isn't the only one who will be curious as to why the FAA has so far refused to adopt biometric ID management techniques even though the Congress has mandated them and the pilots' unions are lobbying for them.
To be as fair as possible, the photo on an ID is a biometric even if a human rather than a computer is used to process it.
