Embodiment 1

[0027] As shown in Fig. 1, a smart card 1 includes a smart card chip 2, on which a microprocessor and a memory with a smart card operating system are arranged.

[0028] Figure 2 describes in detail the structure of the smart card operating system, the layering of the hardware abstraction layer HAL, the core software layer COS and the application layer in the smart card operating system, and the main functional devices of each layer, and identifies the functions of each functional device. The location of the different layers. The smart card operating system structure is divided into three layers. The bottom layer is the hardware abstraction layer, the middle layer is the core software layer, and the top layer is the application layer. Each layer is a relatively independent subsystem. In each layer, several function libraries are set according to the system function requirements; the hardware abstraction layer (HAL) is set with function libraries closely related to hardware, inc...

Embodiment 2

[0036] This embodiment is the structure of the smart card when the smart card is used for the SIM card of the mobile phone to realize the mobile payment function of the mobile phone.

[0037] Fig. 7 is the structure of COS, in which financial application device and SIM card function device are arranged in the application layer.

[0038] Figure 8 describes the functional devices and names that meet the SIM card standard: verifying the KEY device, modifying the CHV device, deactivating the CHV device, sending a short message device, initializing a short message list device, selecting a phone list device, displaying a text device, obtaining answering device, etc.

[0039] In this embodiment, the relevant financial application device and the SIM card function device are properly combined to realize the mobile payment function of the mobile phone with the support of the background system.

Embodiment 3

[0041] In the application layer, there are PBOC2 function library and VIS function library. Combining the PBOC2 function library and the VIS function library described in Figure 9 can realize that the smart card supports the international VISA standard and the Chinese financial integrated circuit card standard at the same time. Domestic and international use.

Abstract

This invention discloses a multi-functional smart card which consists of CMOS chip, micro-processor and memorizer with operating system for the card. There are three layers in the operating system: the Hardware Abstraction Layer, the core software layer and the application layer. Each layer represents a separate subsystem and has several function libraries in it. The chip platform is removable and functional extended.

Description

technical field [0001] The invention relates to a smart card with an embedded operating system, in particular to a multi-application smart card. Background technique [0002] A smart card is an integrated circuit card with a CPU. It is a card that has an integrated circuit chip such as a microprocessor and a large-capacity memory and is embedded on a substrate such as plastic. COS (Chip operating System) is the core technology of the smart card. It is generally developed around the characteristics of the smart card it serves. Its main function is to control the information exchange between the smart card and the outside world and manage the memory in the smart card. And complete the processing of various commands inside the card. [0003] At present, most of the domestic COS are still at the level of an ordinary monitoring program, which is too much attached to the hardware, and is closely integrated with specific applications, and cannot be separated; if the chip platform ...
