Integrated circuit for agreement control

Abstract

A protocol control integrated circuit configured by integrating, on one chip, hardware and control programs necessary for conducting data interchange through communications with portable type media and used in common among various types of apparatus. Thus, the integrated circuit according to this invention is constructed by integrating, on one chip (4), a storage section (2) for storing a control program (5) prepared for protocols for a plurality of digital money types different in mode from each other, a processing section (1) for controlling the handling of the types of digital money, different in mode, by running the control program (5) stored in the storage section (2), and an interface circuit (3) connected to an external circuit including at least one of an external processing section and an external storage section for fulfilling an interface function between the external circuit and the processing section (1). Further, this invention is applicable to various types of transaction apparatus capable of handling, for example, digital money and credit transactions.

Description

technical field [0001] The present invention relates to a protocol control integrated circuit in a system for data exchange and communication with a portable type medium, in particular to a protocol control integrated circuit for processing digital money (electronic money, E-money) and credit transactions Protocol control integrated circuits in various transaction devices, such as ATMs (automated teller machines), ECRs (electronic cash registers), digital money load terminals (digital money load terminals), electronic wallets, POS terminals / handheld POS terminals (handheld POSs ) / POS server constituting the POS (Point Of Sales) system, the role of this integrated circuit is between the above-mentioned various transaction systems and handheld tools containing digital coins [for example, IC (Integrated Circuit) cards] interface device. Background technique [0002] In recent years, interest has been pointing to so-called digital money, which uses electronic digitized data as ...

Problems solved by technology

In addition, in the case where a device handles a plurality of digital coin models with different modes (protocols), it is necessary to develop a control program for each mode of the digital coin, and the test must be performed under the control program related to each protocol, resulting in a test man-hour. Increase

[0010] (2) If approval must be passed, obtaining approval requires a large number of verification results related to the digital currency model, and in order to obtain these verification results, the confirmation work takes a lot of man-hours

However, coverage of the entire device would result in large-scale operations
