Abstract: Computer-implemented method and system are provided for verifying a financial instrument. The method comprises receiving, via a user interface, a request to use a financial instrument. A transaction processor initiates at least one transaction having a variable detail, using the financial instrument, and saves the variable detail. A requested detail relating to the at least one transaction is received via the user interface and the transaction processor compares the stored detail with the requested detail. The transaction processor authorizes the use of the financial instrument in response to receiving the correct input that matches the saved variable detail.

Abstract: Computer-implemented method and system are provided for verifying a financial instrument. The method comprises receiving identification of a source of funds; generating, using at least one processor, a series of verifying transactions involving the source of funds, transaction details of the series of verifying transactions varying from one transaction to another; storing the variable transaction details; initiating the series of verifying transactions; receiving provided transaction details from a user; comparing the variable transaction details with the provided transaction details; and selectively approving the use of the source of funds by the user, based on a result of the comparison of the variable transaction details with the provided transaction details.

Abstract: A new system-level approach to managing the delivery of DC voltage and current. Several system level functions may be enabled without requiring separate ICs to perform those functions. Supervisory functions for a voltage converter may be performed by a central control module or chip that may be coupled to point-of-load voltage converters comprised in digital power management devices (DPMD) through a serial digital bus. The DPMDs may also use the high-speed serial digital bus to provide real-time feedback information to the central control module or chip. Single DPMDs may be combined together in a current sharing configuration in a “plug-and-play” fashion, where the control logic in each DPMD is capable of automatically establishing control loops required a multi-phase supply. Feedback necessary for establishing control may be transmitted across the digital bus coupling the devices.
