Wearable Terminal Multi-Protocol Payment Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems require users to manually operate information terminals to perform payment operations, which can be inconvenient, especially when using wearable terminals that need to support multiple short-range wireless communication protocols for payment processes.
Innovation Solution
A wearable terminal device equipped with both first and second short-range wireless communication units, allowing it to obtain payment information from a payment terminal using one protocol and transmit it to an information terminal via another protocol, enabling payment processing without direct user interaction with the information terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable terminal uses a single short-range wireless communication method to communicate with the payment terminal, then the device complexity is reduced, but the adaptability to different payment terminals is limited
Solution Approach 1:
The wearable terminal incorporates multiple short-range wireless communication units supporting different communication methods (e.g., NFC, Bluetooth, infrared). This multi-functional design enables the terminal to adapt to various payment terminals that support different protocols, resolving the contradiction between adaptability and device complexity by making the device universally compatible through integrated multiple communication capabilities
2Ease of operation
If the user must operate the information terminal to complete payment, then the payment processing reliability is ensured, but the ease of operation is reduced
Solution Approach 1:
The wearable terminal acts as an intermediary device between the user and the information terminal. It receives payment information from the payment terminal, processes the payment autonomously, and only interacts with the information terminal when necessary (e.g., to transmit payment results). This mediator role allows users to perform payments conveniently using only the wearable terminal while maintaining system reliability through controlled interaction with the information terminal
3Adaptability or versatility
If the wearable terminal transmits payment information using the same communication method it received the information, then the communication process is simplified, but the compatibility with information terminals is limited
Solution Approach 1:
The wearable terminal maintains multiple communication units that can receive payment information through one communication protocol and transmit it through another. Instead of converting protocols, the system creates parallel communication paths, copying the information transmission capability across different protocols. This approach enables compatibility with various information terminals while keeping the protocol conversion complexity manageable through dedicated communication units

AI summary
A terminal device includes a first communication unit that performs communication via a first short-range wireless communication method, and a second communication unit that performs communication via a second short-range wireless communication method different from the first short-range wireless communication method. The terminal device further includes an obtaining unit that obtains payment information including information on a monetary amount for goods or a service by using the first communication unit, a confirmation unit that accepts input of information indicating payment approval for the obtained payment information, and a transmission unit that, in response to acceptance of input of the information indicating the payment approval, transmits the obtained payment information to an information terminal by using the second communication unit. The information terminal communicates with a payment server via a network. The payment server performs a payment process related to the obtained payment information.
