Title: Integrated circuit card with liquid crystal display for viewing at least aportion of the information stored in the card

Abstract: An integrated circuit card contains a liquid crystal display for displayingat least a portion of the information stored therein. The displayedinformation is stored in a first, or reserved, memory. A second, oradditional, memory is used to store further information. The use of areserved memory for storing the displayed information permits the use ofvery low power electrical energy sources for driving the display and theelectronics controlling the pixels of the display, such as piezoelectricsources, pyroelectric sources, photovoltaic cells, and very smallbatteries. The first and second memories may be integrated into a singleIC chip, or they may be separate components.
