Unlike isolated internal testing, Plugfest activities allow multiple companies to assess how their technologies interact across different hardware and software ecosystems. Such interoperability testing is increasingly important as consumers expect vehicle access solutions to function seamlessly regardless of smartphone manufacturer, operating system, or automotive brand.

Plugfest #18 has attracted participation from a broad group of global industry leaders spanning automotive manufacturers, technology developers, test laboratories, and engineering specialists. Companies taking part include Apple, AUMOVIO, BMW Group, COMPRION GmbH, DEKRA, Ellisys, Google, Huf Hülsbeck & Fürst GmbH & Co. KG, Hyundai Motor Company, IAV GmbH, InGeek, JLR, Keysight Technologies Inc., Marquardt GmbH, and Robert Bosch LLC.

The involvement of these organizations reflects the growing strategic importance of digital key ecosystems across the mobility sector. Smartphone makers, automotive manufacturers, semiconductor suppliers, wireless technology firms, and validation laboratories all play critical roles in ensuring secure and reliable digital access solutions.

A major highlight of Plugfest #18 is CCC’s expanded focus on Digital Key Version 4. The next-generation version introduces new capabilities aimed at strengthening interoperability across devices and vehicles while improving validation processes across the ecosystem.

One of the key priorities at the event is the introduction of new CCC Digital Key™ v4 test cases. These newly developed testing scenarios are designed to provide deeper validation of next-generation digital key implementations. By expanding the range of test cases, participating companies can better identify potential compatibility issues before products reach the market, reducing risks associated with deployment and customer adoption.

The additional v4 testing scenarios are expected to improve the resilience and reliability of digital key technologies under a broader range of operating conditions. This is particularly important as vehicle access systems become more dependent on wireless technologies and increasingly integrated with smartphones and cloud-based ecosystems.

Another major area of focus at Plugfest #18 is interoperability testing between Digital Key Version 3 (v3) and Version 4 devices. Backward compatibility remains an important consideration for automakers and technology providers, particularly as existing vehicles and devices continue to rely on earlier digital key implementations.

Testing interactions between v3 and v4 technologies allows companies to evaluate how newer systems perform in mixed deployment environments where not all vehicles or consumer devices have migrated to the latest specifications. These real-world compatibility scenarios are essential for ensuring smooth transitions to newer technologies while minimizing disruptions for consumers.

The ability for newer systems to work effectively with legacy technologies is a significant factor in driving mass-market adoption. Consumers expect connected experiences to remain consistent, even as software and hardware evolve over time.

Plugfest #18 also marks an important advancement toward certification readiness through the identification of candidate Interoperability Device List (IDL) devices for Digital Key v4. The IDL process is a critical step in validating devices that can meet interoperability requirements and support certification programs.

By identifying candidate devices early in the process, CCC members can begin preparing for future compliance and certification efforts while ensuring products are aligned with industry standards. Certification readiness ultimately helps create greater trust among automakers, technology providers, and consumers by confirming that devices can reliably support secure vehicle access.

Johnson emphasized the significance of the expanded testing initiatives during this year’s event.

“Plugfest #18 represents an important step forward for CCC Digital Key™ v4, as we expand testing across devices, vehicles, and supporting technologies,” she said. “By introducing new test cases and enhanced validation capabilities, we’re helping members identify and resolve challenges earlier, bringing more robust, interoperable solutions to market faster.”

Beyond Version 4 development, Plugfest #18 introduces several enhanced testing capabilities designed to support more comprehensive validation of digital key systems.

Among the new capabilities are updated Near Field Communications (NFC) test cases, which are being made available for the first time at a CCC Plugfest. NFC technology serves as one of the core communication methods enabling secure proximity-based vehicle access and authentication.

The updated NFC testing framework builds on lessons learned from previous Plugfests and incorporates new insights gained through ongoing technical development. Expanded NFC testing aims to improve the consistency, reliability, and security of digital key interactions, particularly in scenarios involving close-range authentication between devices and vehicles.

Another notable addition is the implementation of Bluetooth® Low Energy (LE) sniffing techniques. These testing approaches strengthen validation of Bluetooth LE-based interactions, which are widely used in passive entry and remote access systems.

Bluetooth LE technology plays a central role in enabling convenient features such as automatic vehicle unlocking when authorized users approach their vehicles. Enhanced testing helps manufacturers validate signal reliability, communication accuracy, and system responsiveness while reducing the likelihood of connectivity failures.

The event also continues to support remote keyless entry and passive entry test scenarios, ensuring that core vehicle access functions remain reliable and secure across diverse operating environments.

These scenarios are particularly important because they replicate real-world vehicle usage situations where users interact with digital key systems in dynamic environments, including crowded parking areas, varying wireless signal conditions, and different device configurations.
