Abstract

L'invention concerne un procédé de paiement NFC, un système de paiement NFC et un terminal mobile. Le procédé de paiement NFC comprend les étapes suivantes : évaluer s'il faut recevoir une demande de découverte provenant d'un dispositif d'acceptation de paiement; si un résultat d'évaluation est affirmatif, acquérir des premières informations d'emplacement géographique actuel à propos du dispositif d'acceptation de paiement; évaluer si les premières informations d'emplacement géographique actuel et des informations d'emplacement géographique préstockées à propos du terminal mobile appartiennent à la même région; si c'est le cas, effectuer le paiement NFC, sinon arrêter le paiement. La solution technique de la présente invention évite le risque dans une transaction que le paiement soit effectué ailleurs après que des informations sensibles à propos d'un utilisateur ont été reproduites ou falsifiées de façon malveillante, et améliore la sécurité de paiement, et améliore ainsi l'expérience d'utilisateur.
