AI-Generated Identities Fuel New Fraud Threat as Digital Payments Turn to Programmable Trust

Generative AI can now mimic voices, faces and even typing rhythms and user behavior, gradually eroding the reliability of voiceprints, selfies and behavioral biometrics used by banks. As AI agents also gain the ability to make payments for customers, risk controls are shifting from a one-time determination of “who you are” to continuous assessments of devices, transaction context and behavioral intent. The change has implications for the foundations of trust in digital wallets and the financial system.

On March 16, 2026, Paymentology Chief Technology Officer Tim Joslyn advocated replacing binary authentication with real-time trust scoring, allowing low-risk transactions to proceed while subjecting high-risk transactions to additional verification. He also proposed using rule-based tokenization to restrict AI agents, such as imposing a limit of just $5. The following day, FIS Vice President Christine Hurtubise called for tokenizing PANs and names and establishing dedicated authentication standards for agents.
