The invention provides protection to wireless portable transponders from unauthorized interrogation by employing a mechanical means for disabling reception by or from the antenna of the transponder. Transponders include RFID tags that are attached to items that a persons may purchase or carry. Such transponders generally have means for receiving and storing electronic and other information, commonly in binary form using memories as in electronic circuits, etc.. The invention is designed to provide privacy of electronic information. The tags can be protected from receiving or providing unauthorized or unwanted information. The invention provides the mechanical means that permit the owner to decide when reception/interrogation of personal or other information is not desired by employing the provided mechanical disable control means.

A method and system for providing risk assessment and management reporting via dynamic total net worth for multi-market electronic trading. The method and system allow risk assessment management and reporting to be determined using current and historical trading losses for dynamically calculated current total net worth values for electronic trading at a trading firm, a trading firm office and a trading account. Risk thresholds are selectively and dynamically configurable for automatically displaying risk information for and automatically disabling electronic trading when risk thresholds are exceeded. Risk information is displayed in two dimensional (2D) and three dimensional (3D) display elements.
