Solution To Prove Interoperability of Your CCC Digital Key Implementation

The CCC Digital Key Test Solution is developed for engineers to prove interoperability and ease the debugging process of NFC- and BLE-based car access solutions in compliance with the latest Car Connectivity standard. It features real-time communication monitoring for seamless capture and analysis of contactless communication. Moreover, our solution offers a functionality for CCC Digital Key™ protocol translation. For the Digital Key based on NFC real-time disturbance of the communication enables engineers to simulate diverse scenarios during comprehensive testing. With its efficient test case management capabilities, the solution facilitates test execution and automation, ultimately delivering dependable and precise results for keyless entry systems.

Our solution was designed specifically to cater to the Car Connectivity Consortium (CCC) Digital Key™, End-to-End Interoperability Test Suite. It serves as a vital tool for automotive companies and device manufacturers engaged in the digital key implementation process.

Who is it for?

Authorized Car Connectivity Consortium members working on the digital key according to CCC standard, including but not limited to:

  • Automotive manufacturers
  • Automotive suppliers
  • Smartphone, and smart device manufacturers
  • Certification laboratories
  • Quality assurance teams

CCC Digital Key Test Solution for NFC

Explore our Car Connectivity Consortium certified test solution for the advanced and secure digital key experience of the future.

CCC Digital Key Certification

The Car Connectivity Consortium unveiled its CCC Digital Key Certification for the Digital Key based on NFC, aiming to establish worldwide compatibility for vehicle and mobile digital key apps using consistent standards and validated tools. COMPRION is the provider of the validated CCC End-to-End Interoperability Test Tool for NFC.



This diagram illustrates the test setup orchestrated by an operator. The operator is auditing the End-to-End (E2E) interoperability tests according to the certification program.

Software components:

  • NFC log viewer
    Displays the NFC protocol with translation into human readable format
  • Test Framework
    Test plan management software running test cases

Hardware components:

  • NFC Sniffer
    NFC traffic monitoring over the air using a spy antenna
  • NFC Disturb Unit
    Jamming communication, causing a deliberate error


Test Bench

The test cases are organized into a test bench, which thoroughly examine the content of the NFC protocol. It then generates results based on whether the expected pattern matches at the correct time. The included test cases encompass the following areas:

  • Owner pairing test cases, including test cases for error handling.
  • Door transaction test cases, including test cases for error handling and friend device handling.
  • Console transaction test cases.
  • Key management test cases for owner and friend digital key termination (offline/online).



CCC Digital Key Test Solution includes the following components that together enable comprehensive testing and verification of NFC-based car access solutions:

  • CL Verify A
    COMPRION's contactless testing tool for validation of contactless interface design.
  • Device Test Center - CCC Edition
    Sophisticated test plan management software and NFC log viewer.
  • CCC Digital Key End-to-End Interoperability Test Bench
    WCC1 (NFC only) according to Car Connectivity Consortium specification.
  • A set of monitoring (spy), and disturb antennas.


Live Bluetooth Message Translation

Our Digital Key Viewer visualizes Bluetooth Digital Key communication and translates it into a human-readable format. This allows a convenient analysis and debugging. It can be used together with an Ellisys Bluetooth Tracker for realtime monitoring or it can import a HCI log-file which was captured on the mobile device.
