Problems solved by technology

The above-mentioned issuance model sometimes cannot meet the requirements of the issuers of the co-branded card. For example, from the perspective of security, the issuers hope that they can fully control their own applications. That is to say, the issuers do not have card issuers and applications on the card. The difference between providers, everyone rents a card together, and they are all equal application providers
In this case, the card issuer and the application provider coexist on a physical card, but they are logically independent from each other. The existing Java Global Platform card cannot support this issuance mode

Embodiment Construction

[0024] The present invention will be described in more detail below by means of examples and drawings, but the following examples are only illustrative, and the protection scope of the present invention is not limited by these examples.

[0025] Such as figure 2 and 3 As shown, a multi-application smart card includes multiple independent virtual cards integrated on a physical card, as well as a JavaCard virtual machine, a smart card operating system and a smart card chip. The JavaCard virtual machine is responsible for interpreting and executing the byte code of the smart card application , the smart card operating system is responsible for managing various hardware resources of the smart card chip.

[0026] Each virtual card corresponds to an application provider, which is used to provide applications. Each virtual card contains a Card Manager, which is used to control the resources of its corresponding virtual card and provide security demonstration services for terminal a...

Abstract

The invention discloses a multi-application Java smart card which comprises a Java Card virtual machine, a smart card operating system and a smart card chip. The multi-application Java smart card is characterized by further comprising a plurality of virtual cards mutually independent; each virtual card is corresponding to one application provider for providing application; each virtual card comprises a Card Manager for independently controlling the resource of the corresponding virtual card to provide the safety verification service of a terminal access corresponding to the virtual card; and each virtual card correspondingly manages the respective Electrically Erasable Programmable Read-Only Memory (EEPROM) for the content management of the virtual card. The smart card can realize that the issuer and the application provider of the smart card coexist on one physical card mutually and independently and have mutually equal status, thereby satisfying the requirement of each issuing partyof co-branded cards.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a multi-application Java smart card with the function of realizing multiple virtual card application environments on a single physical card and its issuing method. Background technique [0002] One card with multiple functions is a technical requirement arising from the expansion of smart card application fields. For example, banks and other industries, especially industries with a large number of users (such as public transportation, social security, communications, etc.) jointly issue multi-application cards, which can increase the number of cards issued. It also brings convenience to cardholders, and at the same time improves the popularity of bank card brands. In the existing co-branded card issuance model, there is a master-slave relationship between the card issuer and the application provider, which is reflected in the card, that is, the card issuer is the controller of all reso...
