Abstract
An interchip for implantation into a gaming chip or token provides a circular array of light-receiving faces arrayed about the circumference of the chip or token. Light received by one face is conducted to the remainder of the faces by a number of internal fingers which communicate light to and from a central portion. The number of fingers and, hence, faces is selected to reflect the value and, hence, authenticity of the chip or token. Racks of such chips may be scanned or illuminated to detect their value or authenticity.
Claims11
An anticounterfeiting device for implantation within a chip or token comprising:
- a generally planar central light-conducting portion;
- and
- a plurality of light-conducting fingers extending from said central light-conducting portion in a generally planar relation to said central portion, each finger terminating in a respective light-receiving face, such that light received by a face of one of said fingers is transmitted through said central portion to the faces of each of the remaining fingers.
Apparatus comprising:
- a generally flat token having a peripheral edge;
- an implant device embedded in said flat token;
- said implant device including a light-conducting central portion and a plurality of fingers each having a light-receiving end face and extending generally radially from said central portion so as to present a plurality of faces arrayed along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof.
A system comprising:
- a plurality of gaming chips of generally circular configuration, each having a peripheral edge;
- means embedded in each of said gaming chips for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces;
- rack means for retaining said chips in a stack;
- and
- light source means for illuminating a plurality of said chips.
Apparatus comprising:
- a gaming chip having top and bottom surfaces and a peripheral edge;
- and
- means embedded in said gaming chip for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces.
Apparatus comprising:
- a generally flat disc-shaped token having a center and a circular peripheral edge disposed at a selected radius from said center;
- an implant device embedded in said flat token;
- said implant device including a light-conducting, disc-shaped central portion of a radius less than the radius of said token, said central portion being located concentrically with said token;
- and a plurality of fingers extending generally radially from said central portion so as to present a plurality of faces of rectangular cross-section spaced at equal intervals along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof, said fingers and light-conducting central portion further lying in coplanar relationship with one another.
