Patent ID: 8543948

Claim:
A non-transitory machine readable storage medium including design data for at least one of designing, manufacturing, and testing a design, wherein, when executed by a processor, the design data implements the design comprising a point-of-sale system unit, wherein the point-of-sale system unit functions as a central server, and wherein the point-of-sale system unit comprises: a circuit board; and a PCI Express interface communicatively coupled to the circuit board and configured to couple, via a PCI Express communication channel, to a PCI Express feature card, wherein the PCI Express feature card is located in a point-of-sale terminal remote from the point-of-sale system unit, and wherein the PCI Express feature card appears architecturally to the circuit board to be located at the circuit board, wherein one or more point-of-sale input/output devices physically coupled to the point-of-sale terminal use the PCI Express feature card to provide input data to the point-of-sale system unit.
