Abstract
Abstract To provide I.C. cards that are reinforced and above all in which the card body is compatible both with using the I.C. in the card and with using a surface of the card that is coated with a film of magnetic material, at least two reinforcing sheets made of different types of reinforcing material are provided so as to adapt the expansion coefficient and the strength coefficient of the card so that both these coefficients lie within a range that is common to both card technologies. It is shown that this provides greater synergy in use of cards having both electronic memory and magnetic memory since in spite of temperature expansion magnetic card shapes are maintained, thereby making it possible to use magnetic tracks that comply with mass data storage requirements for use with magnetic tracks.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
An I.C. card comprising a card body made of plastic whose stiffness is reinforced by strengthening fibers, the card body also being provided with a cavity for receiving an integrated circuit chip provided with means for establishing communication between the chip circuit and the world outside the card, wherein the strengthening fibers are, at least locally, of two different types and are placed in the car body in at least two sheets and in two matrix configurations, wherein the two configurations are intermeshed.
Claim 2
Dependent Claim
83 words

Claim 3
Dependent Claim
107 words
An I.C. card comprising a card body made of plastic whose stiffness is reinforced by strengthening fibers, the card body also being provided with a cavity for receiving an integrated circuit chip provided with means for establishing communication between the chip circuit and the world outside the card, wherein the strengthening fibers are, at least locally, of two different types and are placed in the card body in at least two sheets and in two matrix configurations, wherein the two strengthening sheets are disposed in a belt fixed around the micromodule including the chip prior to the micromodule and its belt being fixed in the car body.
