<p>A method for estimating a risk profile of a user (32, 34, 36) of a personal digital assistant (PDA - 22, 24, 26) includes collecting, using the PDA, data indicative of a travel pattern of the user of the PDA. The risk profile of the user of the PDA is inferred from the travel pattern. The risk profile is output to an external system, so as to enable the external system to provide to the user a commercial offer based on a risk level which is indicated by the risk profile.</p> |
