Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC card systems lack the ability to dynamically limit card functions based on location, leading to increased user processing load and costs due to the need for GPS receivers in mobile terminals to manage multiple applications.
Innovation Solution
A secure device configuration with an authentication section and control section that allows card functions to be changed based on location, using a secure device, terminal apparatus, and gate equipment to authenticate and manage access to specific applications, eliminating the need for user registration and GPS receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS receivers and position detection sections are added to mobile terminals to enable location-based application selection, then card functions can be limited based on location, but device complexity and cost increase
Solution Approach 1:
The patent extracts the position detection function from the mobile terminal and relocates it to the IC card itself. The IC card now contains the GPS receiver and position detection section, while the mobile terminal only needs to display applications based on position information received from the card. This extraction reduces mobile terminal complexity while enabling location-based application selection.
Solution Approach 2:
The patent introduces a position information management section in the mobile terminal that acts as an intermediary between the IC card's GPS receiver and the application selection display. This intermediary component receives position information from the IC card, manages it appropriately, and uses it to control application display order, thereby enabling location-based functionality without requiring the mobile terminal itself to have complex position detection capabilities.
2Adaptability or versatility
If user registration operations are required for location-based card function limitation, then card functions can be customized by location, but user processing load increases
Solution Approach 1:
The patent implements self-service functionality where the IC card automatically performs position detection and provides position information to the mobile terminal without requiring user registration or manual input. The card's embedded GPS receiver continuously obtains position information, and the system automatically manages application display based on this information, eliminating the need for users to perform registration operations for location-based customization.
Solution Approach 2:
The patent performs position detection and application selection preparation in advance through the IC card's continuous position monitoring and the mobile terminal's position information management. By preliminarily obtaining and managing position information before user interaction is needed, the system enables automatic application selection without requiring users to perform registration or configuration operations at the moment of use.
3Adaptability or versatility
If multiple card applications are stored to support multiple functions, then card versatility increases, but memory capacity requirements increase
Solution Approach 1:
The patent implements dynamic application selection based on the IC card's current position information. Instead of requiring all applications to be simultaneously accessible or permanently active in memory, the system dynamically determines which applications should be displayed and used based on real-time location data. This dynamic approach allows the card to support multiple applications while only actively managing those relevant to the current location, reducing the effective memory capacity burden.

AI summary
There are provided a secure device, a gate device, and a device providing a secure device such as an IC card capable of limiting an area where the card application function and the device function are realized. The secure device (20) includes: an authentication application (24) for performing authentication of a gate device (40); a terminal application/setting instruction (26) and a terminal application (27) installed in a mobile telephone (10) as a terminal; and a CPU (23) as control means for installing the terminal application specified by the gate device (40) in the mobile telephone (10) when authentication application (24) has successfully authenticated the gate device (40). The secure device (20) is held over the gate device (40) and only in the area where normally passed, the terminal application/setting instruction (26) and the terminal application (27) are installed in the mobile telephone (10). Since the gate application (43) of the gate device (40) specifies an application which functions in a particular area, a user need not perform registration operation. Moreover, there is no need of mounting a GPS receiver or the like onto the terminal.
