Abstract: An embodiment of the present invention is directed to a Temporal CVV2 of CVV, which may be represented as a temporary three digit number generated using unique credentials associated with a card product. According to an embodiment of the present invention, the Temporal CVV2 may be generated for each transaction request or other defined set of transactions based on one or more factors, including time period/limit, usage, fraud/risk considerations. With this solution, a customer may request a new Temporal CVV2 each time a purchase is initiated. This may include online purchases, e-commerce transactions, manual link and provision requests, customer authentication for servicing channels, etc. An embodiment of the present invention seeks to mitigate risk and provide a safer and secure solution for customers while providing flexibility to make various purchases before a new card arrives.

Abstract: A lift-turn valve actuator is provided for tapered plug valve and slip assemblies that accomplishes vertical movement of the plug and retraction of the slips from sealing engagement with the valve body prior to rotation of the plug member 90.degree. to its open position. The valve actuator assembly includes inner fitting inner and outer sleeve members each having cam slots formed therein with the cam follower of a valve actuating stem being engaged with both cam slots. Rotation of the outer sleeve member with respect to the static inner sleeve imparts initial vertical movement to the actuator stem, valve stem and valve plug for slip retraction as an initial component of movement followed by simultaneous rotational and upward movement of the plug member until the plug member has rotated 90.degree. to its open position.
