Abstract: A financial account proxy system receives a data packet from a first cardholder device. The data packet includes a limited use machine-readable code, receiver information corresponding to a second cardholder device, and one or more limitations. The machine-readable code, receiver information, and limitations are stored. The machine-readable code is associated with a primary account number of a financial account of the primary cardholder. A pre-authorization request message is transmitted to an issuer of the financial account, and pre-authorization details are received from the issuer. The limited use machine-readable code is transmitted to the second cardholder device. A transaction request authorization message is received from a POS terminal. The transaction request authorization message is associated with a transaction performed with the machine-readable code. The transaction request authorization message includes transaction details and the machine-readable code.

Abstract: The present invention provides a method for estimating the average-case activity in a digital circuit. The method includes the steps of assigning initial activity values to outputs of flops in the digital circuit, and repeatedly updating the activity values in an iterative procedure until a predetermined termination criterion is met. The updating of the activity values uses a combination of standard probability updating techniques and predetermined formulae for obtaining the activity values of predesignated types of circuit elements in the digital circuit. The predesignated types of circuit elements include, for example, one or more of a clock-gated flop, an enable flop and a flop with a recirculation multiplexer.
