A smart card having embedded therein and integrated as a part thereof a microchip for storing information on the smart card, electronics for reading the information stored on the smart card and a virtual image display connected to the electronics for providing a virtual image of the information stored on the smart card for viewing at a viewing aperture, the virtual image display including a data input terminal designed to receive image data thereon, an image source and display optics for viewing an image generated by the image source and the display optics being housed within the smart card and optically aligned with the image source and providing an image for viewing at the aperture.

2. A smart card as claimed in claim 1 wherein at least a portion of the display optics are contained within an accessory component capable of optically aligning with the image source housed within the smart card and providing an image for viewing at an aperture.

3. A smart card comprising:

a microchip embedded within the smart card, having a data input terminal and a data output terminal, and capable of storing dataelectronic information thereon;

a virtual image display embedded within the smart card and positioned to provide an image for viewing at a viewing aperture, the virtual image display including a data input terminal designed to receive image data thereon, an image source and display optics for viewing an image generated by the image source and the display optics being housed within the smart card and optically aligned with the image source and providing an image for viewing at the aperture; and

electronics embedded within the smart card and connected to the data output terminal of the microchip for receiving the dataelectronic information contained thereon and further connected to the data input terminal of the virtual image display for supplying image data thereon in response to the dataelectronic information stored thereon the microchip.

4. A smart card as claimed in claim 3 further including at least one user interface control connected to the data input terminal of the microchip.

5. A smart card as claimed in claim 3 wherein the virtual image display includes a two dimensional array of light emitting devices connected to provide a complete image, the two dimensional array being coupled to the data input terminal of the virtual image display for receiving the image data and generating the complete image in response thereto.

6. A smart card as claimed in claim 5 wherein the two dimensional array of light emitting devices includes a two dimensional array of light emitting diodes.

7. A smart card as claimed in claim 6 wherein the two dimensional array of light emitting devices includes a two dimensional array of organic light emitting diodes.

8. A smart card as claimed in claim 5 wherein the two dimensional array of light emitting devices includes a two dimensional array of liquid crystal devices.

9. A smart card as claimed in claim 3 wherein the electronics includes a central processing unit (CPU) and a random access memory (RAM).

10. A smart card as claimed in claim 3 including safety features for preventing unwarranted viewing.

11. A smart card with reader comprising:

a microchip at least partially embedded within the smart card, having a data input terminal and a data output terminal, and capable of storing dataelectronic information thereon;

a virtual image display positioned to provide an image for viewing at a viewing aperture, the virtual image display including a data input terminal designed to receive image data thereon, the virtual image display further including an image source and display optics, the display optics comprised of at least one optical element having a light inlet and a light outlet directed at an angle to the light inlet, with one of a refracting, diffracting and reflecting surface optically positioned between the light inlet and the light outlet so as to direct light from the light inlet to the light outlet, the virtual image display including a two dimensional array of light emitting devices connected to provide a complete image, the two dimensional array being coupled to the data input terminal of the virtual image display for receiving the image data and generating the image in response thereto, and the display optics being housed within the smart card, optically aligned with the image source housed within the smart card and providing an image for viewing at the viewing aperture; and

electronics mounted in the smart card and connected to the data output terminal of the microchip for receiving, and processing dataelectronic information, the electronics further connected to the data input terminal of the virtual image display for supplying image data thereto.

12.
