Abstract
The invention relates to a portable data carrier having a display device. This data carrier contains a microprocessor and storage devices associated with the microprocessor as well as means for displaying data stored in the storage devices associated with the microprocessor. In addition, the data carrier contains a display controller for controlling the display means and an energy supply unit for supplying at least the display unit and its controller with energy. Such a data carrier is to be improved so as to reduce the energy demand for the display unit. This is obtained by a nonvolatile memory disposed separately from the microprocessor and its storage device, said memory being associated with the controller of the display means and containing the data intended for display.
