Abstract

Le problème abordé par la présente invention est d'éliminer la nécessité d'un verrou physique pour une porte déjà installée, et de permettre le verrouillage/déverrouillage même par un utilisateur ne possédant pas de téléphone intelligent. Selon la solution de l'invention, un système de verrouillage/déverrouillage (100) est caractérisé en ce qu'il comprend : un terminal d'acquisition (10) installé de façon à acquérir des informations biométriques d'une personne située devant une porte (D) ; un dispositif de verrouillage/déverrouillage (20) attaché à une barrette tournante (S) qui est disposée sur le côté intérieur de la porte (D) ; et un serveur (30) permettant d'authentifier l'habilitation de sortie/d'entrée pour ladite personne par rapport à la porte en fonction des informations biométriques de la personne. Le système de verrouillage/déverrouillage (100) est également caractérisé en ce que le dispositif de verrouillage/déverrouillage (20) actionne la barrette tournante (S) selon le résultat d'authentification.
