An embodiment of the present invention may be deployed in a mobile payment device configured to communicate with a payment terminal via an RF near-field communication channel. The payment device comprises a sensor to detect and log usage parameters corresponding to behaviors of the user of the payment device. Sensors may take the form of any from movement sensors, light sensors or orientation sensors for example. In order to prevent inadvertent execution of a payment instruction from the terminal, the log of parameters created due to the user's behaviors is compared with a predetermined set of parameters compatible with a user's expected behaviors should he be intentionally performing payment behaviors and payment is only authorized if a match is achieved. |
