Well, actually they can change.... I'm pretty sure my right retina is considerably different today than it was before 2010, when I had radiation and laser treatment for a tumor. Likewise, people can burn their fingers, altering the fingerprints with scar tissue.
Certs are certainly the way to go. What is needed is a way to be able to carry them on you at all times (implant perhaps?), while being able to update it and offer up public information on demand. The downside of this is a loss of anonymity. We already have paranoid people who rant about RFID tracking using our money.
