Abstract

A token for use with a token operated device includes a plurality of predetermined optical characteristics. The plurality of predetermined optical characteristics are disposed in a substantially radially symmetrical manner with respect to the token, and each of the optical characteristics have the property of a facet wherein an effective surface normal of said facet is a line along a predetermined vector angle with an elevational angle ranging preferably between 30.degree. and 60.degree.. An azimuthal angle of the facet surface is other than substantially along a radial line of the token or substantially along a line tangent to an annular ring centered on the token such that a token operated device can validate the predetermined optical characteristics substantially independent of token orientation. A token testing apparatus includes a chute defined by a field adjustable pair of spaced token edge guides spaced a predetermined distance from each other such that each token passing through the chute is sensed along its center.
