Hewlett-Packard Co. in Palo Alto, Calif., has agreed to market payments software from Fidelity National Information Services Inc. to its banking clients.

Fidelity National, a Jacksonville, Fla., technology company, has produced software that is compatible with the California company's systems for more than two decades; it said Wednesday that Hewlett-Packard is now delivering some servers to customers with Fidelity payments applications preinstalled.

Fidelity's DataNavigator back-office transaction support software and its IST switch software for debit transactions are both being delivered on HP's Integrity servers; its Connex debit payment software is available on HP's NonStop Integrity servers and blades.

Martin Fink, a senior vice president at HP and the general manager of its business-critical systems unit, said in a Fidelity press release that offering the payments applications preinstalled will let financial companies "establish a solid competitive advantage with a lower total cost of ownership."
