Embodiment 1

[0019] see figure 2 and image 3 , an embodiment of the present invention provides a method for implementing a multifunctional smart card device, which specifically includes the following steps:

[0020] Step 101: the smart card manufacturer establishes a smart card embedded software system inside the smart card device, and establishes two partitions in the smart card embedded software system;

[0021] Usually, the smart card manufacturer can establish a smart card embedded system that can realize multiple applications according to the corresponding specifications that the smart card application needs to support, such as debit / credit application specifications, security authentication mechanism specifications, etc. Software system, and according to the size of the space required for writing data notified by each smart card application provider in advance, establish a plurality of partitions in the smart card embedded software system for the establishment of the main director...

Embodiment 2

[0042] see figure 2 and Figure 4 , the embodiment of the present invention also provides a method for realizing a multifunctional smart card device, which is basically the same as Embodiment 1, except that the way to realize multi-application selection is different, that is, steps 109 to 110 are different, and the remaining steps 101' to 110 are different. Step 108' is exactly the same as step 101 to step 108 in Embodiment 1, and will not be repeated here. In this embodiment, step 109 to step 110 become:

[0043] Step 109': The smart card embedded software system finds the partition corresponding to the current communication protocol according to the current communication protocol;

[0044] In practical applications, different communication protocols correspond to different application functions, and then realize the multi-functional application of smart card devices;

[0045] Step 110': the smart card embedded software system automatically loads and executes the applicat...

Abstract

The invention discloses an implementation method of a multi-functional smart card device, and belongs to the technical field of embedded software systems of smart cards. The method comprises the following steps: a smart card manufacturer establishes a plurality of partitions in the smart card device, and distributes each partition to a predetermined smart card consumer; the smart card consumer establishes an application home directory in the partition which is distributed by the smart card manufacturer, and establishes a file structure necessary for application under the home directory, and writes in application data; and the smart card device is connected with an application system terminal to finish application selection of the home directory thereof. The method is characterized by establishing a file structure with a plurality of home directories existing simultaneously, and mapping different applications to different home directories respectively, the home directories are independent from each other and do not interfere each other, thus access rights of the applications are independent, and potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the technical field of a smart card embedded software system, in particular to an implementation method of a multifunctional smart card device. Background technique [0002] With the development of smart card technology, smart cards have penetrated into all aspects of people's lives, and have been widely used in finance, communications, transportation, petroleum, catering, social security, taxes and other fields, which greatly facilitates people's lives. However, while people enjoy the convenience brought by smart cards, they also suffer from new troubles brought by smart cards, which are mainly manifested in: people must hold multiple cards to perform different applications, which increases the number of cards per person, which is not only inconvenient The day-to-day management of cardholders, but also caused a waste of resources. In order to use and manage smart cards conveniently and save resources and costs at the same tim...
