Abstract

A microcircuit card (31) comprising a microcircuit and a card body, characterized in that this card body is formed of a base (10) in which is formed a cavity provided with a bottom and an internal part fixed in the cavity and to which the microcircuit is joined, the internal part and the microcircuit (12) together constituting at least a part of a second microcircuit card (11) including at least a part of the body of said second card.

Claims

1. A method of making a microcircuit card assembly comprising the steps of:

providing a base;

providing a preliminary base including a small card having a microcircuit;

personalizing at least the microcircuit of said small card;

separating the small card from the remainder of said preliminary base after said step of personalization; and

attaching said small card to said base, said small card being operational when attached to said base,

wherein the base is provided with a pocket having a width substantially equal to a width of said small card and a length at least as long as a length of said small card so that said small card is held entirely within said pocket when inserted therein.

2. The method of claim 1, wherein said base is more mechanically rigid than said small card.

3. A method of making a microcircuit card assembly comprising the steps of:

providing a base;

providing a preliminary base including a small card having a microcircuit an antenna;

personalizing at least the microcircuit of said small card;

separating the small card from the remainder of said preliminary base after said step of personalization; and

attaching said small card to said base, said small card being operational when attached to said base,

wherein said base is provided with a pocket for attachment of the said small card and is permeable to electromagnetic energy received by said antenna so that said small card is fully operational when held entirely within said pocket.

4. A microcircuit card assembly comprising in combination:

a base comprising an attachment area;

a preliminary base including a small card having a microcircuit, at least said small card being personalized, and said small card being mountable, after separation from a remainder of said preliminary base, in said attachment area so as to be operational when attached to said base,

wherein the base is provided with a pocket having a width substantially equal to a width of said small card and a length at least as long as a length of said small card so that said small card is held entirely within said pocket when inserted therein.

5. The microcircuit card assembly of claim 4, wherein said base is more mechanically rigid than said small card.

6. A microcircuit card assembly comprising in combination:

a base comprising an attachment area;

a preliminary base including a small card having a microcircuit an antenna, at least said small card being personalized, and said small card being mountable, after separation from a remainder of said preliminary base, in said attachment area so as to be operational when attached to said base,

wherein said base is provided with a pocket for attachment of the said small card and is permeable to electromagnetic energy received by said antenna so that said small card is fully operational when held entirely within said pocket.
