Dual Gateway Data Transmission for Payment Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart payment terminals cannot simultaneously transmit data related to payment transactions, software updates, and business applications with distinct transmission constraints, leading to inefficient use of resources and increased costs due to uniform transmission parameters.
Innovation Solution
A method that allows a communications device to establish multiple connections with different gateways, each with unique transmission parameters, enabling the simultaneous transmission of data with varying quality of service, transport protocols, and operator identifiers, thereby accommodating different types of services such as real-time and best effort services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single connection with uniform transmission parameters is used, then device complexity is reduced, but transmission reliability and service adaptability deteriorate because sensitive and non-sensitive data cannot be transmitted with distinct parameters
Solution Approach 1:
The patent segments the transmission channel into multiple connections (first connection for sensitive data, second connection for non-sensitive data), each with distinct transmission parameters. This allows sensitive payment transaction data to be transmitted with high reliability parameters while non-sensitive software update data uses best-effort parameters, resolving the contradiction between uniform complexity and differentiated reliability requirements
Solution Approach 2:
The patent applies local quality by assigning different transmission parameter sets to different data types: the first connection uses parameters optimized for reliability (sensitive data transmission) while the second connection uses parameters optimized for cost-efficiency (non-sensitive data transmission). This localized parameter differentiation resolves the contradiction by providing high reliability where needed without universally increasing complexity
2Adaptability or versatility
If multiple connections with distinct transmission parameters are established, then service adaptability and transmission efficiency are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic connection management where the system automatically selects and establishes appropriate connections based on data type: sensitive data triggers the first connection with reliability parameters, while non-sensitive data triggers the second connection with best-effort parameters. This dynamic adaptation resolves the contradiction by providing service versatility through automated parameter selection rather than manual configuration
Solution Approach 2:
The system performs self-service by automatically determining the appropriate connection and transmission parameters based on the data being transmitted. The terminal device itself manages the complexity of multiple connections by implementing logic that selects the first connection for sensitive data and the second connection for non-sensitive data, eliminating the need for external complex configuration and resolving the adaptability-complexity contradiction
3Productivity
If uniform transmission parameters are used for all data types, then device complexity is minimized, but transmission cost increases due to inability to optimize parameters for different service requirements
Solution Approach 1:
The patent changes transmission parameters based on data type: the first connection uses parameter sets optimized for sensitive data transmission (higher reliability, potentially higher cost) while the second connection uses parameter sets optimized for non-sensitive data (best-effort, lower cost). This parameter differentiation resolves the contradiction by improving transmission efficiency for each data type without requiring complex manual parameter management
Solution Approach 2:
The patent segments the transmission service into two distinct connections with different parameter sets, allowing efficient transmission of sensitive data with reliability parameters and non-sensitive data with cost-optimized parameters. This segmentation resolves the productivity-complexity contradiction by enabling targeted parameter optimization that improves overall transmission efficiency without proportionally increasing management complexity

AI summary
In the field of payment terminals, a new generation of modular, function-rich payment terminals is appearing. Such smart payment terminals transmit, equally well, data relative to payment transactions and, for example, data relative to software updates. However, at present, a smart payment terminal in incapable of transmitting different data in accordance with their respective transmission constraints. This can represent a considerable cost for the merchant. A communications device is therefore provided to set up two connections simultaneously with two different gateways and thus be capable of exchanging data associated with different transmission parameters. Thus, the communications device can simultaneously transmit data relative to different types of services having distinct transmission parameters.
