Abstract

A device and method making the device. The device includes a flat body made of a plastic material. The flat body has at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces. The cavity is adapted to receive an electronic identification device. At least one plug made of a plastic material is included. The at least one plug is adapted to be inserted into the cavity. The electronic identification is retained in the flat body when the at least one plug is inserted into the cavity. The method includes making the flat body, forming the cavity in the flat body, placing the electronic identification device in the cavity, inserting the at least one plug in the cavity, and fixing the at least one plug to the flat body.

Claims

1. A device in the form of, one of, a token or plaque comprising:

an electronic identification device arranged in the cavity;

at least one plug made of a plastic material, the at least one plug being adapted to be inserted into the cavity,

wherein the electronic identification device is completely enclosed and retained in the flat body when the at least one plug is inserted into the cavity.

2. The device of claim 1, wherein the one of, a token or plaque is one of a gaming token and a gaming plaque.

3. The device of claim 1, wherein the electronic identification device is one of:

retained on one side by the at least one plug and on another side by the flat body; and

retained on one side by the at least one plug and on another side by another plug.

4. The device of claim 1, wherein the at least one plug comprises a shape which is substantially similar to a shape of the cavity and wherein the plug is sized to fit within the cavity with a minimum clearance.

5. The device of claim 4, wherein the at least one plug is secured to the flat body by one of glueing, welding, and mechanical interlocking.

6. The device of claim 5, wherein the at least one plug is secured to the flat body by mechanical interlocking, the mechanical interlocking being formed by one of deformation by heating and compression.

7. The device of claim 6, wherein the at least one plug comprises at least one beveled surface.

8. The device of claim 1, wherein the at least one plug is secured to the flat body by welding and wherein the welding utilizes heating and pressure.

9. The device of claim 8, wherein the heating and pressure are applied to the at least one plug and to the at least two parallel faces.

10. The device of claim 1, wherein the cavity comprises a through opening which extends between the at least two parallel faces and wherein the at least one plug comprises at least two plugs.

11. The device of claim 10, wherein the electronic identification device is disposed within the flat body between the at least two plugs.

12. The device of claim 1, wherein the cavity comprises a blind opening which opens to at least one of the at least two parallel faces, the blind opening comprising a flat bottom surface for supporting the electronic identification device.

13. The device of claim 1, wherein the electronic identification device comprises an electronic circuit, memory storage, and an emitter-receiver having a peripheral antenna.

14. The device of claim 13, wherein the flat body comprises one of a rigid plastic shell and a hardened coated resin pellet.

15. The device of claim 14, wherein the flat body comprises a hardened coated epoxy resin pellet.

16. The device of claim 1, wherein the electronic identification device comprises a diameter which is smaller than a diameter of the cavity, the cavity comprising a bottom surface and a lower surface which is stepped below the bottom surface.

17. The device of claim 1, wherein the flat body and the at least one plug comprise one of a polymer material and a material which can be welded.

18. The device of claim 1, wherein the flat body and the at least one plug comprise a thermoplastic material.

19. The device of claim 18, wherein the thermoplastic material comprises one of a styrene, a styrene copolymer, PBS, ABS, a methacrylic, PMMA, a vinyl, PVC, a PVC copolymer, a cellulose, cellulose acetate, a saturated polyester, PBC, a polyolefin, PE hd, and a PE hd copolymer.

20. The device of claim 1, wherein one of the flat body and the at least one plug comprise a thermoplastic material having a vitreous transition temperature of between 40°

C. and 130°

C.

21. The device of claim 20, wherein the vitreous transition temperature is between 50°

C. and 100°

C.

22. The device of claim 1, wherein the flat body and the at least one plug comprise a thermosetting plastic material.

23. The device of claim 22, wherein the thermosetting plastic material comprises a non-saturated polyester material.

24. A method of making a device comprising a flat body made of a thermosetting plastic material, the flat body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces, the cavity being adapted to receive an electronic identification device, at least one plug made of a thermosetting plastic material, the at least one plug being adapted to be inserted into the cavity, wherein the electronic identification is retained in the flat body when the at least one plug is inserted into the cavity, the method comprising:

making the flat body;

forming the cavity in the flat body;

placing the electronic identification device in the cavity;

inserting the at least one plug in the cavity; and

fixing the at least one plug to the flat body.

25. The method of claim 24, wherein the fixing comprises welding.

26. The method of claim 24, wherein the fixing comprises heating and applying pressure to one of the at least one plug and the flat body.

27. The method of claim 24, further comprising shaping the contour of the flat body by cutting.

28. The method of claim 27, further comprising removing sharp edges from the contour of the flat body by finishing.

29. A method of making a device comprising a flat body made of a plastic material, the flat body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces, the cavity being adapted to receive an electronic identification device, at least one plug made of a plastic material, the at least one plug being adapted to be inserted into the cavity, wherein the electronic identification is retained in the flat body when the at least one plug is inserted into the cavity, the method comprising:
