kwelch007 writes I run a network for a company that does manufacturing primarily in a clean-room. We have many systems in place that track countless aspects of every step. However, we do not have systems in place to identify the specific user performing the step. I could do this easily, but asking users to input their AD login every time they perform a task is a time-waster (we have "shared" workstations throughout.) My question is, what technologies are people actually using successfully for rapid authentication? I've thought about fingerprint scanners, but they don't work because in the CR we have to wear gloves. So, I'm thinking either face-recognition or retinal scans...but am open to other ideas if they are commercially viable.
