Case Study: World's Largest Quick-Service Restaurant achieves 100% payment uptime and reduces PCI burden with ACI Worldwide Hosted Payments

ACI Provides Hosted Payments Solution for One of the World’s Largest Retailers

World’s Largest Quick-service Restaurant partnered with ACI Worldwide to solve a critical payments challenge: deliver fast, always‑available, and scalable payment processing across more than 14,000 U.S. locations while reducing the operational burden of PCI compliance and preparing for future payment technologies. The QSR needed a solution that could handle very high volume (around 150 transactions per second) and remain online 24/7.

ACI Worldwide implemented its hosted payments solution with an active/active redundancy design, 24/7 monitoring, and point‑to‑point encryption, allowing the retailer to add stores and new payment methods without in‑house infrastructure work. The result: ACI Worldwide delivered 100% uptime, eliminated downtime costs, reduced PCI compliance overhead, freed IT staff and capital for strategic initiatives, and improved corporate credibility with franchisees, producing measurable time and cost savings.
