QR Target Bridging Between Mobile Payment Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment service providers (MPSPs) with different transaction QR-code formats cannot facilitate cross-network transactions without a common payment interface or national QR standard, as they lack incentives to adopt such standards.
Innovation Solution
A method and system for target bridging between MPSPs using an emulator system that resolves and transmits QR codes or other targets across different payment networks, enabling transactions through issuer and acquirer management systems with emulator accounts and bridging transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each MPSP uses its own QR code format for transactions, then transaction compatibility within the same network is maintained, but cross-network transactions become impossible
Solution Approach 1:
The patent introduces a bridging system as an intermediary component that sits between different MPSP networks. This bridging system includes a translator module that converts QR code formats between different MPSPs and a bridge account that facilitates fund transfers. The intermediary enables cross-network transactions without requiring each MPSP to adopt a common standard, thus maintaining format reliability while achieving cross-network adaptability.
Solution Approach 2:
The patent changes the parameter of QR code format compatibility by introducing a translation layer that maps different QR code formats to a universal internal representation. The system maintains the original QR code formats for each MPSP while transforming them into a common internal format for processing, enabling cross-network transactions without altering the fundamental format parameters of individual networks.
2Adaptability or versatility
If a common payment interface or national QR standard is adopted, then cross-MPSP transactions become possible, but implementation complexity and resistance from MPSPs increase
Solution Approach 1:
Rather than requiring all MPSPs to integrate with a common standard directly, the patent uses a bridging system as an intermediary that handles the complexity of format translation and network connectivity. This approach reduces the complexity burden on individual MPSPs while enabling cross-network transactions.
Solution Approach 2:
The patent creates a virtual copy of the bridging system's translator and bridge account infrastructure that can be instantiated for different MPSP combinations. This copying approach allows the system to handle multiple MPSP networks without requiring each network to implement the full common standard, reducing overall system complexity.
3Adaptability or versatility
If MPSPs integrate their systems through APIs and common targets, then cross-network transactions are enabled, but the incentive structure for MPSP adoption weakens
Solution Approach 1:
The bridging system acts as an intermediary that absorbs the integration complexity and technical challenges, allowing MPSPs to participate in cross-network transactions without having to build complex integration capabilities themselves. This improves the ease of adoption for MPSPs while maintaining cross-network capability.
Solution Approach 2:
The bridging system provides universal access to multiple MPSP networks through a single interface. The bridge account and translator components can work with different MPSP formats and networks, creating a multi-functional platform that incentivizes MPSP adoption by providing broad compatibility without requiring each MPSP to develop specialized integration capabilities.

AI summary
The present invention relates to a system and method for target bridging between a portable device of a payer of a first service provider and a merchant device of a receiver of a second service provider different from the first service provider. An emulator system is used to login the payment system of the second service provider with a bridging account, so that the first service provider may conduct transactions with the second service provider via the bridging account, even if the first service provider runs a target format different from the second service provider.
