1. A method of controlling operation of one or more functions performed by an item, the method comprising:
- illuminating a token including one or more luminescent markers;
detecting emission from the one or more luminescent markers in response to the illumination;
generating a spectral signature from the detected emission;
comparing the generated spectral signature with one or more pre-defined spectral signatures associated with authorization to perform/access/use the one or more functions; and
allowing operation of one or more of the one or more functions performed by the item when the generated spectral signature matches one or more of the one or more pre-defined spectral signatures.

Abstract
A method of controlling operation of one or more functions performed by an item comprises illuminating a token including one or more luminescent markers and detecting emission from the markers in response to the illumination. A spectral signature from the detected emission is generated and compared with one or more pre-defined spectral signatures associated with authorization to perform, access, or use the functions. Operation of one or more of the functions is allowed when the generated spectral signature matches one or more of the pre-defined spectral signatures.

12. A device for controlling operation of one or more functions performed by an item, the device comprising:
-
an illumination source which illuminates a token incorporating one or more luminescent markers;
a detector which detects emission from the one or more luminescent markers in response to the illumination; and
a processor which (i) generates a spectral signature from the detected emission, (ii) compares the spectral signature with one or more pre-defined spectral signatures, and (iii) allows operation of one or more of the one or more functions performed by the item when the generated spectral signature matches one of the one or more pre-defined spectral signatures. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
