Key Block Compliance Deadline Looming

A crucial update for secure cardholder data protection is approaching! The Payment Card Industry (PCI) mandates the adoption of TR-31 key block technology for all ATM key transfers, with a firm deadline of January 1, 2025. Older ATMs must undergo upgrades to meet the new EPP version and software requirements.

What Does This Mean for Your FI?

  • Upgrade your EPP version:  Ensure your ATMs have the necessary EPP version to support TR-31. Software for testing with your host processor is available.

  • Hardware compatibility:  If you purchased a new ATM after 2020, it will likely be compatible. Are you still trying to figure it out? Ask NuSource; we can help determine if you need to upgrade.

  • Honor upgrade deadlines:  Don’t wait until the last minute! Plan and schedule your upgrades now to avoid potential delays and a last-minute rush closer to the January 2025 hardware expiration.


Non-Compliance Consequences

ATM shutdown: Failure to comply will result in your ATM being disabled and unable to process transactions. Your host processor will stop accepting transactions from non-compliant ATMs on or before the deadline.


Take action now:

Contact your NuSource representative today to discuss your upgrade options and schedule your transition to ensure compliance before the critical deadline.


Remember, a seamless customer experience is crucial for your business and customer trust. Don’t get caught off guard by the approaching deadline and a dead ATM. Act now.
