NFC Token Delivery for Serverless Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the challenge of accessing restricted goods or services from a server without knowing the server's address, requiring manual search or authentication processes.
Innovation Solution
A system utilizing short-range wireless communication, such as NFC, between a terminal and a portable device to transmit a digital token, allowing users to access services without entering or searching for the server's address, where the token can be used multiple times and includes authentication data for secure delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually search for or enter server address to access restricted goods or services, then authentication and access control can be implemented, but user convenience and accessibility are reduced
Solution Approach 1:
The server address and authentication credentials are pre-configured in the terminal device before the user needs to access the service. When the user initiates access, the terminal automatically retrieves and transmits these pre-stored credentials to the server, eliminating the need for manual input while maintaining security through pre-established authentication mechanisms.
Solution Approach 2:
The terminal device automatically performs the authentication process without requiring user intervention. The system self-manages credential transmission, server communication, and authentication verification, allowing users to access services simply by being in proximity to the terminal rather than manually entering server addresses or credentials.
2Ease of operation
If server address is hardcoded or pre-configured in terminal devices, then user convenience is improved, but system flexibility and adaptability are reduced
Solution Approach 1:
The terminal device dynamically determines which server to access based on real-time conditions such as user location, service type, and terminal capabilities. Rather than being statically configured for a single server, the system adaptively selects appropriate servers from multiple available options, allowing both automatic access convenience and flexible adaptation to different service scenarios.
3Reliability
If authentication processes are implemented before service delivery, then security is improved, but access speed and user experience are reduced
Solution Approach 1:
Authentication credentials are pre-configured and stored in the terminal device before access is needed. When the user approaches the terminal, authentication data is immediately transmitted to the server without requiring real-time user input or complex authentication sequences, thereby maintaining security while significantly reducing access time and improving user experience.

AI summary
The system (10) has a terminal (800) e.g. metro access device, comprising a near field communication (NFC) short-range wireless communication unit (82) to emit a signal (SIG) with a digital token (TOK). A portable device i.e. Universal serial bus (USB)key (500), has an NFC short-range wireless communication unit (52) to receive the signal. A terminal (600) e.g. personal computer, has a communication unit for sending the token to a server (700). The server has a delivery unit to deliver good i.e. digital object (OBJ), or service based on the reception of the token. An independent claim is also included for a method for delivering a good or service.
