Abstract

L'invention concerne un dispositif de terminal et un procédé de reconnaissance d'empreinte digitale. Selon différents états d'un dispositif terminal, différents capteurs d'empreintes digitales peuvent être utilisés pour la reconnaissance d'empreintes digitales, de sorte que à la fois la sécurité de la vérification d'empreintes digitales et l'expérience d'utilisateur peuvent être prises en considération. Le dispositif terminal comprend : un premier capteur d'empreinte digitale, un second capteur d'empreinte digitale, et un processeur, le premier capteur d'empreinte digitale étant intégré dans un écran du dispositif de terminal, le second capteur d'empreinte digitale étant situé à des positions, autre que l'écran, dans le dispositif terminal, et le processeur est utilisé pour contrôler, en fonction de l'état du dispositif terminal, les modes de fonctionnement du premier capteur d'empreinte digitale et du second capteur d'empreinte digitale.
