Patent number: 11640605Abstract: A method, server and storage medium for verifying a transaction using a smart card are disclosed. A server receives a transaction request to perform a transaction with a user of the smart card. The transaction request includes identification information and encrypted data extracted from the smart card, and transaction information. The server determines a user account linked to the identification information. The server performs a first verification process to authenticate the smart card by verifying that the smart card possesses a correct decryption key corresponding to the identification information. The server performs a second verification process to authenticate the smart card by verifying that the encrypted data extracted from the smart card encodes stored data corresponding to the respective user account linked to the identification information. If the first and the second verification processes are successful, the server processes the transaction in accordance with the transaction information.Type: GrantFiled: November 23, 2020Date of Patent: May 2, 2023Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Kai Liu, Yaxuan Zhu, Runda Cai, Zhenyu Xu, Chenglin Liu
