A security badge to be worn by a person seeking access to a secure system. The badge includes a data processor having a non-volitile and a volitile memory, a transceiver, and an attachment sensor. The volitile memory stores information related to the wearer's security clearance. This information is loaded after the badge is attached to the person and the person's identity is verified. This information is deleated from the volitile memory if the badge is removed from the wearer or subjected to tampering. The data processing system has sufficient computing power to allow the badge to execute encrypted communications with the security system. |
