How to Stop Your AI Agent from Draining Your Bank Account: A Guide to Agentic Payments

Short summary

AI agents handling payments create a 'Human-Not-Present' security crisis because traditional fraud systems assume conscious human intent. Fix this using Verifiable Digital Credentials, transaction-level authentication, scoped payment tokens that restrict merchant access and spending caps, and hard-coded guardrails that prevent agents from making unauthorized purchases. Never give agents raw credit cards—give them cryptographically signed permission slips with strict limits and expiration times.

• •AI agents need payment controls to prevent hallucination-driven overspending
• •Use cryptographic credentials and transaction-level auth instead of session-based access
• •Implement deterministic guardrails that hard-code spending limits and merchant restrictions
