A Christian blogger named Elwood Sanders like this: "Let me state my position clear: NO BIOMETRIC ID CARD! PERIOD! Every evangelical Christian needs to say NO to this kind of thing."

The case of Moss Bluff Elementary highlights our current reality with biometric ID technology: It's becoming so mainstream that schools are using it in their cafeterias. But some people are rejecting it based on religious grounds.

So will pervasive biometric ID be adopted? Or rejected? The answer is less clear than you might think.

Opposition to biometric ID is pretty widespread, and most of that opposition is based not on prophecy, but on concerns about privacy.
