Navigating the Complexities of Global Payments: Visa’s Innovative Use of AI
Visa, a leader in global payments, operates across more than 200 nations and territories, each presenting distinct and complicated regulatory environments.
Addressing Regulatory Challenges with AI Support
The client services team at Visa is tasked with understanding these intricacies to respond accurately to policy-related queries—such as “Are we authorized to process this payment type in this specific country?” However, it’s impractical for any individual to memorize all these regulations.
Traditionally, gathering relevant information has been a painstaking manual task that could take several days depending on data availability.
With the advent of generative AI, Visa identified an extraordinary opportunity to integrate technology by utilizing retrieval-augmented generation (RAG). This not only accelerates information retrieval up to 1,000 times faster but also provides citations for the data retrieved.
“Initially, we see better quality results,” explained Sam Hamilton, Senior Vice President of Data and AI at Visa. “There’s also improved efficiency; they can process far more inquiries than before.”
Visa is leveraging generative AI across its operations through a carefully constructed multi-layered technology infrastructure that helps manage risks while mitigating fraud.
The Birth of Secure ChatGPT: Ensuring Data Safety
The launch date of November 30, 2022—the debut of ChatGPT—marked a significant shift in the landscape of artificial intelligence.
Shortly thereafter, waves of employee curiosity emerged within Visa about accessing ChatGPT functionality. Common queries included “Where can I find my ChatGPT access?” or “Can I utilize ChatGPT?”
Given its stature as one of the foremost digital payment networks globally, Visa must prioritize customer data security—ensuring sensitive information remains confidential and safeguarded against misuse during external model training sessions.
To reconcile employee interest with safety concerns regarding user data protection, Visa rolled out ‘Secure ChatGPT,’ an internal solution operating behind a firewall on Microsoft Azure. This setup allows them stringent control over incoming and outgoing communications via advanced data loss prevention mechanisms.
“All our extensive petabytes worth of information is encrypted and secured both when stored and during transmission,” Hamilton elaborates.
Despite carrying ‘ChatGPT’ in its name, Secure ChatGPT functions as a multi-model interface comprising six distinct options: OpenAI’s variants (like GPT), Mistral models from Hugging Face; Anthropic’s Claude; Meta’s LLaMA; Google’s Gemini; and IBM’s Granite model framework. Hamilton describes this system as “model-as-a-service,” or RAG-as-a-service solution framework designed for flexibility in application integration.
This arrangement enables teams not only access various APIs that suit their unique needs but minimizes constraints associated with shadow IT or unauthorized software usage. According to Hamilton: “Secure GPT merely acts as an intermediary for model utilization.”
Benefits Beyond Secure ChatGPT
Moreover, every developer at Visa receives access to GitHub Copilot for assistance throughout their coding processes—from comprehension enhancement through improved code verification methods—to streamline testing procedures efficiently!
“The coverage concerning code quality escalates substantially thanks to having such support systems available,” noted Hamilton about Copilot benefits aiding development workflows effectively!
Applying RAG-as-a-Service Effectively
Among the most impactful applications envisioned by implementing Secure ChatGPT lies in addressing localized policy inquiries unique per geographic area or jurisdiction!
“With operations spanning countless regions grappling varied legal stipulations makes document management exceed beyond thousands…” remarked Hamilton! With frequent updates influencing compliance standards requiring accuracy remains imperative!
Now armed armed with robust RAG capabilities founded upon reliable real-time datasets ensures responsiveness whereby users immediately retrieve requests bolstered through proper sourcing cues!
This advancement transforms time-consuming investigative endeavors often lasting hours—even days—into solutions provided within minutes! As per insights shared from previous statistics enhanced query performance times hover near two minutes maximum now!” exclaimed Hamilton excitedly regarding innovation progress achieved thus far!
