As the ATM and payments ecosystem rapidly evolves, so do the standards that govern it. One of the most pressing changes facing financial institutions, processors and Original Equipment Manufacturers (OEMs) is the shift toward PCI PIN’s TR-34 standard for key management. While full enforcement may still feel distant, the time to act is now.
What Is TR-34 and Why Does It Matter?
TR-34 is a standard defined by the PCI Security Standards Council that outlines a secure method for distributing symmetric keys using asymmetric (public key) cryptography. In short, it introduces a safer, automated and more scalable way to handle cryptographic keys between hosts and devices.
It is part of a broader industry move toward stronger encryption practices and the retirement of insecure, legacy key-loading methods, especially those involving clear-text keys or manual key entry.
Why Prepare Now?
Although TR-34 compliance is not yet mandatory across all regions or devices, regulators and card brands are strongly encouraging early adoption. As we’ve seen with other PCI initiatives, waiting until the last minute can lead to rushed implementations, operational disruptions and compliance risks.
Being proactive about TR-34 offers several benefits:
- Improved security through the elimination of manual processes
- Reduced key management overhead
- Future-proofing infrastructure
- Compliance readiness ahead of deadlines
Steps to Take Today
Conduct a Key Management Audit
Start by assessing your current key-loading practices. Are you still using manual key loading (MKL)? Are your key exchanges still dependent on paper-based processes or insecure methods?
Look for gaps in:
- Physical security controls
- Key injection workflows
- Documentation and tracking
Understand Your Equipment’s Compatibility
Not all ATMs or Hardware Security Modules (HSMs) are TR-34 ready. Work with your vendors, or contact TSS, to determine:
- Which devices support TR-34 today
- What firmware or hardware upgrades may be required
- If a remote key-loading platform like A98-RKL is supported
Start Planning Your Migration Strategy
TR-34 implementation isn’t plug-and-play. It requires:
- Generating key pairs
- Setting up secure key exchange infrastructure
- Updating procedures and training your team
Invest in Remote Key Loading
If you haven’t already adopted Remote Key Loading (RKL), now is the time. Not only does RKL significantly streamline key management, but platforms like the TSS A98-RKL are also TR-34 ready, providing you with a future-proof solution that scales with compliance needs.

Engage with Your Vendors and Partners
Ensure your ATMs, HSM, and core banking software are also on the path to TR-34. Collaboration is key—literally.
Ask:
- Is your equipment ready for TR-34?
- How are your vendors preparing for the change?
- What’s the timeline for upgrades?
