As the new year begins, the CarMen project continues its steady transition from concept to real-world validation. After establishing the technological and ethical foundations out, the consortium has reached an important milestone: the successful completion of its first experimental testing activities. These initial tests mark a key step toward CarMen’s vision of non-stop biometric border control operating under real operational conditions.
Their objective was to move beyond controlled laboratory environments and assess how CarMen’s biometric technologies perform in realistic border-crossing scenarios, where travellers are often in motion, environmental conditions are unpredictable, and the time available for identity verification is limited.
In line with the project’s ambition to enable “biometrics on the move,” three complementary experimental scenarios were implemented. These included pre-authentication of stationary travellers before border crossing, biometric identification of pedestrians moving continuously through corridors, and on-board verification of passengers inside buses or coaches. Each scenario reflects concrete operational practices at external EU borders and allowed the technologies to be tested under challenging conditions such as movement, variable lighting, changing camera angles, and partial occlusions.
The results of these first tests contribute directly to improving the robustness and reliability of biometric algorithms, validating the combined use of RGB and near-infrared imaging, and advancing image processing techniques for identification on the move. At the same time, the activities strongly reflect the objectives set out in the CarMen project proposal, particularly the ambition to enable seamless, non-stop biometric verification for pedestrians and vehicles without requiring travellers to stop or present physical documents.
Beyond technical performance, the experiments also support a broader reflection on the ethical, legal, and societal aspects of biometric border control. In line with the project’s design, all testing activities are carried out with a strong focus on data protection, privacy, and compliance with GDPR and European legal frameworks, reinforcing CarMen’s commitment to trustworthy and socially acceptable solutions. As the project moves into its next phases of development and pilot demonstrations, these first experimental tests represent a decisive step from vision to implementation. CarMen continues to transform research ambitions into practical solutions that support smoother travel, enhanced border security, and a more sustainable future for European mobility.
