Abstract
A security system includes a first security badge having a visual portion that varies according to signals provided to the first security badge and an authorization server that periodically provides signals to the first security badge in response to a query of the authorization server by the first security badge while the first security badge remains in a controlled zone, the signals varying independently of reader access of the first security badge. The first security badge may be read by a reader only in connection with initial entry into the controlled zone. Authorization of a user of the first security badge may vary while the user remains in the controlled zone. The first security badge may include a visual image of a user of the first security badge and displays additional information. The additional information may include name and authorization status of the user.
