Embodiment Construction

[0023] The foregoing and other technical content, features and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the accompanying drawings.

[0024] See Figure 1 with figure 2 , the preferred embodiment of the financial transaction system of the present invention includes a smart card 1, a terminal 2, and a remote host 3. Smart card 1 has a microprocessor 11, a random access memory (RAM) 12, a read-only memory (ROM) 13, a non-volatile memory (non-violate memory) 14, a card interface unit 15, and an encryption Module (cryptographic module)16.

[0025] A plurality of computer program codes are stored in the read-only memory 13, including a card operating system (COS) 111 (see image 3 ), JCRE (java card runtime environment), and necessary drivers, etc., can be captured and executed by the microprocessor 11. Non-volatile memory 14, such as EEPROM, is used to store application programs 1...

Abstract

This invention relates to the data process method between intelligent card and terminal, which comprises the following steps: selecting one of application program through terminal application program interface and inputting a parameter through terminal to initiate the selected application program; then processing the parameter by the selected application program; finally sending the status response message to the terminal executed by the application program to make the terminal execute special functions according to the information.

Description

technical field [0001] The present invention relates to a financial transaction system, in particular to a financial transaction system utilizing a terminal and a smart card for financial transactions and having a distributed processing architecture. Background technique [0002] A smart card is an IC card, which is a credit card-sized plastic card embedded with an integrated circuit chip. In addition to having a memory storage function, it can also perform data processing and calculation functions. Due to its security Compared with the previous magnetic stripe card, its performance and functionality are better, so it has gradually been widely used in various cards such as telephone cards, stored value cards, and personal identification cards. Especially in financial transaction systems, general merchants often use terminals (or card readers) to read data on smart cards in order to perform actions such as money transactions and data records. [0003] In the previous financi...
