The field of access control is evolving from basic digital key solutions toward highly advanced biometric systems integrated with artificial intelligence. Initial developments focused on biometric fingerprint locks and digital credentials, such as smartphone-based keys and smart cards. These systems allowed for user profile management, custom permissions, and time-restricted access, providing more flexibility and security than traditional metal keys. Mobile applications also introduced administrative roles to manage intercoms and user settings remotely. Subsequent advancements have integrated artificial intelligence to enhance recognition accuracy and prevent spoofing. New technologies combine AI with 3D facial recognition using infrared sensors to map facial structures, alongside fingerprint technology that detects living tissue through temperature and pressure. High-end security models have further expanded to include vein recognition in fingers and palms to verify blood circulation, ensuring the user is a real person. Recent trends show that AI integration continues to expand into smart home security, utilizing advanced biometric authentication methods to enhance residential safety. This occurs alongside broader shifts in the AI landscape, including the emergence of niche consumer devices that utilize cloud-based AI via APIs rather than on-device processing.
