Abstract

A chip card including a flexible body; at least one semiconductor chip supported within the flexible body and comprising a memory for storing the information; a display element capable of displaying at least a portion of the information stored in the semiconductor chip, the display element being supported within the flexible body and comprising display areas viewable from at least one side of the chip card; circuitry for controlling the display element; the chip card being capable of undergoing flexing of the type and magnitude experienced by a card during normal use, handling, and storage (e.g., storage in a pocket, wallet, or purse) without permanent damage to the display element and without permanent loss of the displayed information. A chip card may include a power source to provide multi-media capabilities by driving a speaker/microphone or showing a series of images to produce an animated display or film clip.

Claims

1. A chip card for providing portable storage of information, the chip card comprising:

a flexible body;

at least one semiconductor chip supported within the flexible body and comprising a memory for storing at least some of the information;

at least one display element capable of displaying at least a portion of the information stored in the semiconductor chip, the display element being supported on or within the flexible body and comprising one or more display areas viewable from at least one side of the chip card;

the display element being capable of being flexed, without permanent damage, into the shape of the chip card in the vicinity of the display element when the chip card is placed in a machine that applies torsion to its short sides, the maximum displacement being 5 degrees (plus or minus 1 degree) in alternative directions.

3. The chip card of claim 1 or 2 wherein substantially all of the information on the display prior to said flexing continues to be displayed after said flexing.

2. A chip card for providing portable storage of information, the chip card comprising:

a flexible body;

at least one semiconductor chip supported within the flexible body and comprising a memory for storing at least some of the information;

at least one display element capable of displaying at least a portion of the information stored in the semiconductor chip, the display element being supported on or within the flexible body and comprising one or more display areas viewable from at least one side of the chip card;

the display element being capable of being flexed, without permanent damage, into the shape of the chip card in the vicinity of the display element when the chip card is placed in a machine that applies torsion to its short sides, the maximum displacement being 15 degrees (plus or minus 1 degree) in alternative directions.
