Abstract

The invention discloses a smart card application realization method and system supporting multiple sets of personalized data, belonging to the technical field of smart card applications. The present invention adds environmental authentication files and auxiliary operator application files to the smart card application, which are respectively used to store the environmental authentication data and the auxiliary operator application data; Authenticate the external device environment; if the authentication is passed, confirm the auxiliary operator application data to which the external device belongs; then load the auxiliary operator application data into the smart card application for the smart card application to perform corresponding business processing. On the one hand, the present invention avoids the installation of multiple applications of the same smart card under the condition of multiple uses of one card, which greatly saves the storage space of the card; Cardo played a positive role.

Description

technical field [0001] The invention belongs to the technical field of smart card applications, and in particular relates to a smart card application realization method and system supporting multiple sets of personalized data. Background technique [0002] With the popularity of smart cards and the expansion of application fields, smart cards have gradually become an indispensable tool in modern life. At present, there are many card issuers of smart cards, including banks, telecommunications, municipalities, property management and so on. The applications on smart cards are also diverse and repetitive, for example, the e-wallet application of the transportation card used in the field of public transportation, and the application of debit and credit in the financial field. Among them, the one-card electronic wallet application can also be applied to many fields such as transportation, supermarkets, theaters, public telephones, etc., and the financial debit and credit applica...
