An organic light-emitting diode (OLED) display device used as an identifier of an entity, person, or user access level in an identification badge. With the illustrative embodiments, the access and/or identifying information displayed on the badge can be altered or concealed as needed. The identification badge comprises at least one OLED display device for displaying identification information about a user associated with the identification badge. The identification badge also comprises one or more buttons affixed to the identification badge for selection by the user. User selection of a first button on the identification badge conceals visibility of the identification information displayed in the OLED display device. User selection of a second button on the identification badge enables the identification information concealed from display in the OLED display device to become visible again.
