Security Service Federal Credit Union simultaneously upgraded 10 applications suites connected to its core account-processing system that interface with more than 65 other major applications, the vendor Fidelity National Information Services Inc. announced Wednesday.

The $5.3 billion-asset credit union in San Antonio went live with the system over the Fourth of July weekend, FIS said.

The 10 Systematics application suites included approximately 15,000 modules interfacing with more than 65 applications in Security Service's technology infrastructure, FIS said.

The upgrades included improvements to the integration of channel services — such as the Internet, interactive voice response and mobile banking — to the Systematics core.

"These latest enhancements will not only help reduce our application maintenance costs by eliminating the need for much of the customized code that has accumulated over the years, but will also increase our competitiveness in the marketplace by improving our delivery of premium products and services and enabling our future growth for the next decade and beyond," said Jay Winslow, a senior vice president at Security Service and its chief information officer, in FIS' press release.
