Problems solved by technology

[0005] However, the existing intelligent security products represented by the above-mentioned products generally have the following deficiencies: some of these products do not configure storage devices, but only have simple computing capabilities or provide very simple flag information; some only configure Volatile memory devices can only temporarily store information and cannot meet various data processing requirements; Save very simple information: For products with a storage capacity of less than 1K bytes, it can only be used for single-value applications, such as amount accounting, counting, etc.; products with a capacity of 1K to 8K bytes can generally only store short text , tables, values, and key information, such as personal identity information, ticket information, etc.
[0006] It can be seen that the storage capacity of existing intelligent security products is low, correspondingly their information processing capacity is also poor, and the data transmission and communication methods are single
As a result, the existing intelligent security products can only realize a predetermined single function, perform simple data exchange with a specific card reader and a data processing host according to a predetermined process, and even only perform one-way data transmission, and cannot meet the needs of users. Dealing with data information in complex situations is not suitable for applications in various occasions and systems
These greatly limit the scope of application and extended functions of this type of product

Abstract

This invention provides an integration circuit card system, which comprises the integration circuit card used to store user information; read machine to read the said integration circuit card; data process machine to control the said integration card and read machine, wherein, the read machine and / or integration card has large storage unit used to exchange the data among the integration circuit card, read machine and data process machine. This invention system not only realizes the secrecy and protection of data but also ensures the data validity and integrality.

Description

technical field [0001] The invention relates to an integrated circuit card and its reader-writer, in particular to an integrated circuit card system for realizing large-capacity storage. In addition to realizing security authentication and encryption and decryption functions, the system also has a large-capacity data storage function, and can realize Various data exchange methods within the system. Background technique [0002] With the rapid development of computer network communication technology, e-commerce and information encryption technology, it is urgent to use security products with high security performance, easy operation and low price to protect important data information of customers. [0003] Among the currently existing smart security products, the more representative one is a smart card system composed of a smart card (abbreviated as an IC card) and its supporting card reader and a data processing host. The smart card includes control, storage and interface l...
