NFC Device Configurable Notification Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near-field communication (NFC) devices require specific application program planning to communicate transaction information, which is inflexible and application-dependent, making it difficult to manage and configure centrally for different applications.
Innovation Solution
A near-field communication device that establishes a channel with an external device and provides notifications to a second host processor about the nature or content of application data, configuring these notifications based on parameters such as the application identifier, communication technology, or protocol, using a notification program that identifies and analyzes application data to generate appropriate notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specific application program planning is used to communicate transaction information, then transaction information can be communicated between processors, but the system becomes inflexible and application-dependent
Solution Approach 1:
The notification program is designed to serve multiple applications universally without requiring application-specific programming. It automatically identifies application data, determines the target host processor, and generates notifications for any application running on the secure processor, making the system adaptable to different applications while maintaining reliable communication
2Adaptability or versatility
If application-specific notification configuration is implemented, then each application can be customized, but centralized management becomes difficult
Solution Approach 1:
The notification program operates autonomously without requiring external configuration for each application. It automatically identifies application data types, selects the appropriate target host processor using a routing table, and generates notifications independently, eliminating the need for complex centralized management while maintaining application-specific adaptability
3Ease of operation
If data routing is handled by application programs, then data can be directed to appropriate processors, but the system lacks centralized control
Solution Approach 1:
The notification program acts as an intermediary between the secure processor and host processors. It receives application data, consults a routing table to determine the target processor, and manages the notification process centrally, providing both ease of operation and centralized control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables centralized, flexible management of transaction information across various applications without relying on specific application programs, allowing for application-independent notification configuration and improved data handling in NFC transactions.
Implementation Method 1
Near field communication techniques, called NFC ('Near Field Communication'), allow two devices each comprising an antenna coil to exchange data by inductive coupling. The creation of an NFC communication channel requires that one of the two devices, called 'reader', emits a magnetic field

AI summary
The invention concerns a near field communication device (D2) configured to establish a near field communication channel with an external device (EDV), and provide a first host processor (HP1) with application data (CAPDU) transmitted by the external device. The device is configured to provide a second host processor (HP2) with notifications (NCj, NRj) relative to the nature or content of application data provided to the first host processor (HP1), and to configure the notifications on the basis of a characteristic parameter of an application in the context of which the external device sends data to the first host processor.
