1. A system for determining the registry of transportation modalities, comprising:
- a substrate carried by a transportation modality, said substrate having plural regions exhibiting plural light reflection properties,a scanning device for interrogating a transportation modality by directing an optical beam at the transportation modality, receiving reflected light from the substrate on said transportation modality, and determining coded values associated with said reflected light,a library of stored known values that represent known coded values,said coded values associated with said reflected light being compared with said library of values to determine if the scanned transportation modality is registered.

Abstract
A system and method for determining encoded information borne by transportation modalities. The system includes substrates carried by the modalities and an optical interrogation device capable of remotely acquiring the information and comparing it with a database of acceptable information incorporated into or proximal to the system. The encoded information is provided on the substrate in a matrix of zones exhibiting different optical properties. The matrix of zones and the associated properties constitute a code which is interrogated and read by the system.

15. A method of providing item identification comprising:
-
providing a layer of material having an array of zones thereon, each of the zones having a unique optical reflection frequency, interrogating said coded information provided by said array of zones on said layer with a transmitted optical light beam, receiving light reflected by said array of zones, said light being reflected in a pattern that represents a code, and determining the values of the coded information provided by the reflected light frequencies. - View Dependent Claims (16)
