Abstract: Methods and apparatus for enhancing the security of wireless transactions through the use of position information are provided. In particular, methods and apparatus are provided for wirelessly receiving information relating to a position of a wireless electronic device by a self-service terminal, and taking action on some or all of the steps of a wirelessly received transaction depending on the position information.

Abstract: 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.

Abstract: A self-service terminal (10) such as an ATM has a secure enclosure (12) and an external column (14) extending from the secure enclosure (12). The column (14) has a bore (54) for routing electrical conductors and one or more access slots (58) connecting the bore (54) with an external surface (52) of the column (14). A module (40,42) is mounted onto the column (14) using a bracket (50) defining a channel (94) through which the module's electrical conductors (88) are routed. The electrical conductors (88) are routed from the bracket (50) to a central processor within the secure enclosure (12) by means of an access slot (58) and the bore (54). The modules (40,42) are height adjustable relative to the secure enclosure (12).
