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 from the plurality of chip sensors to a central processing unit (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, 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;

  • characterized in that the plurality of chip sensors includes a photosensor and the filter material comprises a 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, wherein the card material is separate and distinct from the matrix; and

    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, wherein the signal of the contact-bound or contactless inductive communication is a binary value received via the contact-bound or contactless inductive communication and the signal supplied by the plurality of chip sensors is a binary value received via the photosensor; and

    wherein the CPU composes a binary code, which triggers a further process in the chip, from the binary value received via the contact-bound or contactless inductive communication and the binary value received via the photosensor.
