Abstract

The invention relates to a standard card having an embedded mini chip card which is connected with the standard card body by connecting areas. The connecting areas are severed largely or completely and interrupted by small slots. The slots prevent stresses within the mini chip card, and the mini chip card can be easily separated from the standard card body.

Claims

1. A standard card having a main body and a mini chip card bounded by a peripheral edge embedded in the main body, the mini chip card including an electronic module and being totally separated from the main body in certain areas by slots extending over a small part only of the peripheral edge relative to the total peripheral edge and connected with the main body by connecting areas along the remaining peripheral edge, the connecting areas consisting of largely severed sections of the main body extending along the remaining peripheral edge of the mini chip card.

2. The standard card having an embedded mini chip card of claim 1, wherein the connecting areas are defined by opposed cuts or incisions into the main card body from opposed sides thereof leaving a remaining relatively thin core of main body material.

3. The standard card having an embedded mini chip card of claim 2, wherein the remaining core has a thickness of 150-450 microns between the opposed cuts.

4. The standard card having an embedded mini chip card of claim 3, wherein the remaining core has a thickness of about 300 microns between the opposed cuts.

5. The standard card having an embedded mini chip card of claim 1, wherein the mini chip card has lengthwise and transverse sides intersecting at corner areas, and the connecting areas take up substantially the entire lengthwise and transverse sides of the mini chip card.

6. The standard card having an embedded mini chip card of claim 5, wherein the mini chip card has rounded corner areas whereat the slots are located and the connecting areas extend up to 1 to 3 mm from the rounded corners of the mini chip card and intersect the slots at the corner areas.

7. The standard card having an embedded mini chip card of claim 1, wherein the slots are formed by a process selected from the group including punching and milling.

8. A standard card having a main body and a mini chip card bounded by a peripheral edge embedded in the main body, the mini chip card including an electronic module and being totally separated from the main body in certain areas by slots extending over a small part only of the peripheral edge relative to the total peripheral edge and connected with the main body by connecting areas along the remaining peripheral edge, the connecting areas comprising totally severed sections of the main body extending along the remaining peripheral edge of the mini chip card so as to leave the connecting areas compressively connected together in a press fit relationship.

9. The standard card having an embedded mini chip card of claim 8, wherein the mini chip card has lengthwise and transverse sides connecting at corner areas and the connecting areas take up substantially the entire lengthwise and transverse sides of the mini chip card.

10. The standard card having an embedded mini chip card of claim 9, wherein the mini chip card has rounded corner areas whereat the slots are located and the connecting areas extend up to 1 to 3 mm from the rounded corners of the mini chip card and intersect the slots at the corner areas.

11. The standard card having an embedded mini chip card of claim 8, wherein the slots are formed by a process selected from the group including punching and milling.

12. A method for producing a standard card having a mini chip card embedded therein, the standard card including a main body having a thickness and the mini chip card being bounded by a peripheral edge in the main body, the mini chip card including an electronic module and being totally separated from the main body in certain areas by slots extending over a small part of the peripheral edge relative to the total peripheral edge and connected with the main body by connecting areas along the remaining peripheral edge, comprising largely severing the mini chip card from the main body along the connecting areas through the main body thickness so as to leave a relatively thin core of main body material and forming the slots by removal of main body material.

13. The method for producing a standard card having a mini chip card embedded therein according to claim 12, wherein the connecting areas are largely severed at the same time the slots are formed.

14. The method for producing a standard card having a mini chip card embedded therein according to claim 13, wherein the slots are formed by punching main body material.

15. The method for producing a standard card having a mini chip card embedded therein according to claim 13, wherein the slots are formed by milling main body material.

16. The method for producing a standard card having a mini chip card embedded therein according to claim 12, wherein the step of severing the main body material is carried out by using directly opposed cuts on the body material, said cuts extending partially through the main body thickness.

17. A method for producing a standard card having an mini chip card embedded therein, the standard card including a main body having a thickness and a mini chip card being bounded by a peripheral edge, the mini chip card including an electronic module and being totally separated from the main body in certain areas by slots extending over a small part of the peripheral edge relative to the total peripheral edge and connected with the main card body by connecting areas along the remaining peripheral edge, comprising severing the mini chip card from the main card body along the connecting areas without removal of main body material and forming the slots by removal of main body material while leaving the connecting areas compressively connected together in a press fit relationship.

18. The method for producing a standard card having an mini chip card embedded therein according to claim 17, wherein the slots are formed by punching main body material.

19. The method for producing a standard card having an mini chip card embedded therein according to claim 17, wherein the slots are formed by milling main body material.

20. The method for producing a standard card having a mini chip card embedded therein according to claim 17, wherein the step of severing is carried out by using opposed cuts into the main body from opposed sides of the main body.
