At same time ,it introduces the applications of public transportation IC card system in China.

The public transportation IC card charge system is take the non-contact lC card as the prepaid card payment means, take the computer system as the information processing method security reliable modern management system, speeds up the bus charge speed, enhances the operation efficiency, by facilitates the general residents, guarantees the user benefit.

This paper gives summary introduction of the development,characteristic and syntactic structure of embedded database(SQLite);gives a detailed compiling process from SQLite to ARM architecture;and gives concrete application of SQLite through a public traffic IC card data management system based on ARM-Linux embedded system.

This paper studied the applications of data mining technique to bus intelligent card data processing.

With the extend of bus Intelligent Card(IC), getting bus passenger flow information data from bus IC becomes one method.

The bus IC cards generate massive operation data, so using these data can reflect the characteristic of public transport passenger flow accurately on time.

Connecting with the application of IC card system in the real esta te management of Taiyuan No.

The data consistency of IC card system is that the information stored in IC card must be rigorous consistent with the information stored in computers of IC card system, the pivotal problem is that the exchange information must be recorded in IC card and the exchange computer consistently.
