Abstract
The present invention is directed to a gaming chip with a machine-readable symbol encoding a unique identifier for use in a casino environment and methods for producing the same. The present invention prints symbols and human-readable symbols onto a substrate where at least the symbol is machine-readable. The portions of the substrate having the printed symbols, human-readable symbols, or both can be formed into three-dimensional chip members such that the printed surfaces remain on the interior region of the chip member and readable from a region exterior to the gaming chip by a scanner or optical device. The chip members can be integrally formed into a gaming chip through the injection of filler material between the chip members. The injection molding process structurally and integrally bonds the respective chip members together.
