A reader for validating a secure tag. The reader comprises: an optical source operable to illuminate the secure tag; a processor coupled to the optical source and operable to activate and de-activate the optical source; and a luminescence detector coupled to the processor and operable to measure a luminescence spectrum after a time delay has elapsed. The time delay may be based on a number generated by the reader in a random or pseudo-random manner, or it may be received across a network from a remote server. The processor is operable to accessing the time delay and to derive a luminescence signature from a luminescence spectrum measured by the luminescence detector. The processor is then operable to create a control signature using the time delay, to compare the derived luminescence signature with the control signature, and to validate the secure tag in the event of a match.

Secure tag validation

A self-service terminal ( ) such as an ATM has a secure enclosure ( ) and an external column ( ) extending from the secure enclosure ( ). The column ( ) has a bore ( ) for routing electrical conductors and one or more access slots ( ) connecting the bore ( ) with an external surface ( ) of the column ( ). A module ( ) is mounted onto the column ( ) using a bracket ( ) defining a channel ( ) through which the module's electrical conductors ( ) are routed. The electrical conductors ( ) are routed from the bracket ( ) to a central processor within the secure enclosure ( ) by means of an access slot ( ) and the bore ( ). The modules ( ) are height adjustable relative to the secure enclosure ( ).
