A protective garment, which is intended to be only worn by a wearer who is authorized to pass through a security perimeter, comprises a pocket, which defines a window, a flap, which is movable between a position wherein the flap covers the window and positions wherein the flap does not cover the window, and a card, which is disposed in the pocket. The card displays or records data, which are readable through the window by a human, by an electronic reader, or by both, and which are unique to the authorized wearer of the protective garment. The data may comprise symbolic data, such as bar code data, and may comprise a photograph of the authorized wearer of the protective garment. When the flap covers the window, the flap protects the data against becoming illegible because of foreign matter, such as soot, or because of surface abrasion.
