How many of you would be willing to give up full biometrics for a passport. Would you be willing to give a computer 4 biometrics that can be checked by a computer quickly.
Fingerprints, retina scan, height and some non intrusive DNA.
This would be more reliable than name, date of birth and location. There are some non criminal types with non readable finger prints.
Once again we would have to place everyone in the system and it could be used in all sorts of legal ways to aid local law enforcement. We do ask government employees to be fingerprinted so why not for passports.
