Abstract

A method for forming a medium is provided. In accordance with the method a base layer is provided. A material layer is formed on the base layer. The material layer has void. A transponder having a memory is positioned in the void. A medium is also provided. The medium has a base layer and a material layer having a void. A transponder having a memory is positioned in the void.

Claims

1. A medium comprising:

an antenna layer forming an antenna on a base layer;

a transponder with having a memory and an interface patterned to cooperate with the antenna, the transponder having a thickness;

a material layer on the antenna layer, the material layer having a void sized to receive the transponder; and

an overcoat layer on the material layer with the overcoat layer adapted to permit the formation of an image thereon,

wherein the void has void walls that are formed from an elastic material and arranged so that the void walls are elastically deformed during insertion of a transponder into the void and respond to the elastic deformation in a manner that holds the transponder in the void with the transponder positioned in the void to cooperate with the antenna; and

wherein said void walls define a void with an outer portion near an outer surface of the material layer and an inner portion proximate to an inner surface of the material layer near an antenna, said outer portion having a width that is less than a width of the transponder so that as the transponder is inserted into the outer portion, the outer portion elastically deforms to allow the transponder to pass into the inner portion and then expands to capture the transponder.

2. The medium of claim 1, wherein said antenna comprises an antenna forming material.

3. The medium of claim 1, wherein the antenna layer comprises a layer of antenna material having an etched antenna pattern.

4. The medium of claim 1, further comprising an overcoat layer on the base layer opposite the material layer, said overcoat layer adapted to permit the formation of an image thereon.

5. The medium of claim 1, further comprising an adhesive layer.

6. The medium of claim 1, wherein said transponder has a thickness within a predefined range and said material layer has a thickness at least equal to a thickness of the transponder.

7. The medium of claim 1, wherein said base layer has a bottom surface adapted to permit the formation of an image thereon.

8. The medium of claim 1, wherein said base layer has a bottom surface coated with a material upon which an image can be formed.

9. The medium of claim 1, wherein said material layer is formed from a material that permits the formation of an image thereon.

10. The medium of claim 1, wherein the base layer is formed from a material that permits an image to be formed thereon.

11. The medium of claim 1, wherein said antenna layer is printed onto the base layer.

12. The medium of claim 1, wherein said overcoat layer is adapted to provide protection against at least one of chemical, radiation, mechanical, electrical or optical damage.
