Build Quantum-Safe Payments Readiness Plan Now
Summary
NACHA and its Payments Innovation Alliance Quantum Payments Project Team published guidance urging payments industry participants to build multi-year quantum-safe implementation plans. The guidance identifies "Harvest Now, Decrypt Later" (HNDL) as a systemic risk where the weakest cryptographic link threatens all participants. Organizations are advised to follow a three-phase quantum-safe readiness implementation road map covering assessment, planning, and migration.
What changed
NACHA published guidance calling on payments industry participants to take immediate action on quantum computing threats to payment system cryptography. The document emphasizes that "Harvest Now, Decrypt Later" attacks represent a systemic risk where any participant's weak cryptographic implementation puts the entire network at risk. A three-phase implementation road map is referenced for organizations seeking to develop quantum-safe readiness plans.\n\nAffected parties—financial institutions, third-party providers, vendors, and other payments participants—should treat this as an early advisory to begin strategic planning for quantum-resistant cryptography. While no compliance deadline or penalty is stated, the guidance signals that quantum readiness is becoming a risk management imperative for the payments ecosystem.
What to do next
- Review the Quantum-Safe Payments Readiness Implementation Road Map
- Conduct a quantum-safe payments risk assessment
- Develop a multi-year quantum-safe implementation plan covering three phases

The payments industry cannot wait for the arrival of a cryptographically relevant quantum computer to act. Payments participants – financial institutions, third parties, vendors, and more – should have already started their quantum readiness implementation plan to address the looming quantum threat. "Harvest Now, Decrypt Later" (HNDL) isn’t just a technical risk, it’s a systemic risk – where the weakest link puts all participants at risk.
Your multi-year quantum-safe implementation plan should cover three phases. Access a detailed Quantum-Safe Payments Readiness Implementation Road Map.
