Bottom line: As AI agents begin making payments for users, banks and fintechs must distinguish authorized automation from fraud within milliseconds.

India’s payment ecosystem is becoming an early test bed for this problem because UPI transactions settle instantly. Moneycontrol reports that payment firms are increasingly using AI to combine thousands of behavioral signals for real-time risk assessment, while Razorpay’s Vulcan model is designed to make payment decisions in milliseconds.

Why it matters: Agentic commerce changes the fraud-control problem from detecting suspicious automation to determining whether an automated action is actually authorized, within the same speed constraints as the payment itself.
