Abstract

The invention relates to a data carrier (100) with a chip (10) which stores energy (13) as well as information for contact-bound or contactless inductive communication, and with a plurality of excitable chip sensors (11) integrated in the chip (10), which, after excitation (12), pass on a signal (18) to a CPU (19) of the chip (10), in which the signal (18) is processed. The invention is characterized in that, independently of storing energy (13) as well as information by the chip (10), the excitation (12) is specifically adjustable by the chip (10) for the purpose of additionally storing information and is adaptable to the requirements of processing the signal (18) in the CPU (19).

Claims

1. A data carrier with a chip, which stores energy as well as information for contact-bound or contactless inductive communication, and with a plurality of excitable chip sensors integrated in the chip, which, after excitation, pass on a signal to a CPU of the chip, in which the signal is processed, characterized in that, independently of storing energy as well as information by the chip, the excitation is specifically adjustable by the chip for the purpose of additionally storing information and is adaptable to the requirements of processing the signal in the CPU.

2. A data carrier as claimed in claim 1, characterized in that the plurality of chip sensors communicates with a filter material in which the excitation is specifically adjustable and is adaptable to the requirements of processing the signal in the CPU.

3. A data carrier as claimed in claim 2, characterized in that the filter material consists of card material.

4. A data carrier as claimed in claim 2, characterized in that the filter material consists of document material.

6. A data carrier as claimed in claim 4, characterized in that the document material is formed as an additive.

7. A data carrier as claimed in claim 1, characterized in that the plurality of chip sensors includes a photosensor detecting the excitation of a pulsed laser beam.

8. A data carrier as claimed in claim 1, characterized in that the CPU performs a combined processing operation on a signal of the contact-bound or contactless inductive communication and the signal supplied by the plurality of chip sensors.

9. A data carrier as claimed in claim 2, characterized in that the plurality of chip sensors includes a photosensor and the filter material consists of card material which is opaque at wavelengths of less than 800 nm and transparent at wavelengths of 800 to 1100 nm, and of a UC converter adjoining the card material, as well as an interference filter laminate adjoining the UC converter, in which a pulsed laser beam first penetrates through the card material and then penetrates the UC converter.

10. A data carrier as claimed in claim 2, characterized in that the plurality of chip sensors includes a photosensor and the filter material consists of the card material and a matrix adjoining the card material, which matrix generates modulated luminescences, in which a pulsed laser beam first penetrates through the card material and then penetrates the matrix.

11. A data carrier as claimed in claim 2, characterized in that the plurality of chip sensors includes at least two identical or different photosensors whose filter material is different, in which the filter material consists of the card material, and in which a pulsed laser beam penetrates through the filter material and excites the photosensors which separately pass on a signal to the CPU.

12. A data carrier as claimed in claim 2, characterized in that the plurality of chip sensors includes a photosensor and the filter material consists of a light converter which shifts wavelengths, and of card material adjoining the light converter, which card material is transparent in a wavelength range between 800 and 1100 nm, while a pulsed laser beam penetrates the light converter only.

13. A data carrier as claimed in claim 1, characterized in that the data carrier is integrated in a value or security document.

14. A method of communicating with chips integrated in data carriers, in which energy as well as information from a chip is stored for contact-bound or contactless inductive communication and, independently thereof, a plurality of chip sensors integrated in the chip is excited, which then pass on a signal to a CPU for the purpose of processing, the excitation being specifically adjusted by the chip for the purpose of additional storage of information and being adapted to the requirements of processing in the CPU.

15. A method as claimed in claim 14, characterized in that the plurality of chip sensors is caused to communicate with a filter material in which the excitation is specifically adjusted and adapted to the requirements of processing the signal in the CPU.
