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,

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

2. The method of claim 1, wherein the base is a telephone.

3. The method of claim 1, wherein the step of attaching said small card to said base includes the use of adhesive.

4. The method of claim 1, wherein the said small card which is operational when attached to said base comprises an antenna.

5. The method of claim 1 further comprising the step of providing the base with a through-hole and the step of passing a key ring through said through-hole.

6. The method of claim 1 wherein the preliminary base is substantially rectangular with a length of about 85 mm and a width of about 54 mm.

7. The method of claim 1 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.

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

9. The method of claim 4 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.

10. The method of claim 1 wherein a periphery of said base is at least partially rounded.

11. 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 this small card being personalized, and this small card being mountable, after separation from a remainder of said preliminary base, in this attachment area so as to be operational when attached to this base.

12. The microcircuit card assembly of claim 11, wherein the base is a telephone.

13. The microcircuit card assembly of claim 11, wherein the step of attaching said small card to said base includes the use of adhesive.

14. The microcircuit card assembly of claim 11, wherein the said small card which is operational when attached to said base comprises an antenna.

15. The microcircuit card assembly of claim 11 further comprising the step of providing the base with a through-hole and the step of passing a key ring through said through-hole.

16. The microcircuit card assembly of claim 11 wherein the preliminary base is substantially rectangular with a length of about 85 mm and a width of about 54 mm.

17. The microcircuit card assembly of claim 11 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.

18. The microcircuit card assembly of claim 11 wherein said base is more mechanically rigid than said small card.

19. The microcircuit card assembly of claim 14 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.

20. The microcircuit card assembly of claim 11 wherein a periphery of said base is at least partially rounded.
