Patent attributes
A method and system enables users of a system such as a mass transit system to receive status information about the system. The information may relate to one or more stops or vehicles along various routes of the system. The user is provided with a display device, and one or more readers are positioned throughout the system. The display device includes a display screen that displays system status information, a driving circuit, an antenna and an inductive coil. When the display device's inductive coil is in the presence of a proximate electromagnetic field and the antenna receives a data signal, the inductive coil delivers power to the driving circuit, and the driving circuit causes the display screen to display updated system status information.
