Patent ID: 8754863

Claim:
A fixed display system operable to interact with a separate mobile communication device, comprising: a display system including a fixed display operable to display information; a first sensor coupled to the display system and operable to provide a first signature and first timestamp upon detecting an occurrence of a predetermined event; a second sensor coupled to the communication device and also operable to provide a second signature and second timestamp upon detecting the occurrence of the same predetermined event; and a processor operable to compare the first and second signatures and timestamps and determine whether these first and second signatures describe the same predetermined event that identifies and authenticates the communication device, whereupon the processor initiates a communication session between the display system and the communication device such that the communication device performs a personalized action as a proxy for the display system without the communication device providing any personal information to the display system, wherein the display system provides a set of actions for the communication device to perform using personal information stored on the communication device.
