RFID technology is changing the way nuclear plants are assuring the safety of their guards and communities. Georgia-based iQuest has implemented a safer, more foolproof system that enables guards to verify the identity of a carload of people without ever leaving their stations.

But it's not just useful for the high-security world of nuclear energy; RFID key tags are beginning to replace password-based access to better control machine security on the plant floor.

This is generally being implemented at the user end, but more OEMs and integrators might be asked to pay increasing attention to security concerns. How much are you thinking about the security of the access to the machines you’re building? Should it be more? Less?
