AI Technical Summary

Problems solved by technology

First, most terminals in use today do not support this selection mechanism, nor are they able to recognize the associated ATR
Therefore, smart cards using this mechanism can only be compatible with new terminals designed to support application selection, and cannot be used on most existing terminals
Second, designers and / or software programmers of terminals and terminal equipment must expend considerable time, effort and resources to incorporate such selection mechanisms into their products

Embodiment Construction

[0023] In the specification and drawings, the same reference numerals denote the same elements.

[0024] refer to figure 2 , the multi-application smart card 20 contains at least four conventional applications specified by available ATRs, which are supported by conventional terminals 10, 12, 14, 16. A persistent storage unit 22 on the smart card 20 holds information indicating which of the four applications is to be run. The persistent storage unit 22 may be EEPROM or FLASH memory, or other type of memory that retains its data when the smart card is not powered. According to the above description, it should be understood that when the smart card 20 is inserted into the terminal, a mechanism or scheme must be provided to change or change the value stored in the persistent storage unit 22 to the value of the required application, so as to prevent the wrong application from running.

[0025] refer to Figure 3A , to start the multi-application smart card operation, the user i...

Abstract

A multi-application smart card has a persistent storage unit. The persistent storage unit stores data and / or information that indicates which application is to be run the next time the smart card is inserted into a terminal. The persistent storage unit may indicate the same application, a different user-selected application, or an application-selection application is to be run next. Alternatively, the persistent storage unit may indicate the next application on a predefined list as the application to be run next. An application-selection terminal allows a user to manually select the user-selected application. The terminal may initiate communication with the smart card by sending a special, predefined signal to the smart card.

Description

[0001] This application claims the filing date of US Provisional Patent Application No. 60 / 059,382, filed September 19,1997. technical field [0002] The invention relates to a smart card, in particular to smart card application selection of a multi-application smart card. Background technique [0003] Smart cards have a wide range of applications, such as electronic game cards, bank cards, and identity cards. Smart cards are often enclosed in a protective, plastic or metal casing, are about the size of a credit card and contain one or more embedded integrated circuit components. Terminals, such as electronic gaming machines, vending machines, and ID identification systems, are known to employ one or more smart card interfaces for connecting smart cards to these terminals. [0004] Conventional terminals have built-in communication protocols to support smart card applications. These agreements usually require the smart card to provide an answer signal (ATR) of RESET immedi...
