Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current financial transaction systems, particularly smart cards and mobile wallets, face limitations in integrating multiple debit and credit accounts securely and efficiently, with restrictions on dynamic EMV and NFC chips, and low user adoption of smartphone-based mobile wallet technology.
Innovation Solution
A dual-layer smart card/phone system that combines a master unit with a touchscreen and slave unit, enabling secure transactions through magnetic, optical, and NFC communication, with a hybrid approach using magnetized contact points, optical data transceivers, and RF cancellation signals to enhance security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dynamic EMV or NFC chips are included on a dynamic smart card, then secure payment information storage and transmission is improved, but financial institutions do not allow for dynamic EMV or NFC chips to be included on a dynamic smart card
Solution Approach 1:
The system divides the transaction device into two separate layers: a static smart card layer containing secure EMV chip and magnetic stripe elements, and a dynamic master unit layer containing NFC capability and display interface. This segmentation allows each layer to maintain its specialized functions while working together as an integrated system, resolving the conflict between secure static storage and dynamic adaptability
Solution Approach 2:
The patent introduces magnetic contact points as an intermediary mechanism between the static smart card layer and the dynamic master unit layer. These magnetic contacts enable secure data transmission when the layers are coupled together, providing a reliable communication interface that bridges the static secure element and the dynamic interface without requiring dynamic chips in the card itself
2Ease of operation
If smartphone-based mobile wallet technology is used, then access to multiple accounts is improved, but user adoption remains low and market has been declining
Solution Approach 1:
The system creates a physical copy of the smartphone wallet functionality in the master unit, which can store and manage multiple payment account data sets locally. This allows users to access multiple accounts without relying on smartphone connectivity or mobile wallet applications, providing a more reliable and standalone solution that doesn't depend on declining smartphone-based mobile wallet technology
Solution Approach 2:
The patent transitions from a purely digital smartphone-based wallet to a hybrid physical-digital system with two layers. The master unit provides a physical interface with display and input capabilities, while the slave unit (smart card) provides secure physical storage. This dimensional shift from digital-only to physical-digital hybrid addresses user concerns about relying on smartphone applications
3Adaptability or versatility
If a single computerized transaction device is used, then access to multiple debit and credit accounts is improved, but device complexity increases
Solution Approach 1:
The transaction device is segmented into two independent but complementary layers: a static smart card layer for secure storage and a dynamic master unit layer for interface and processing. This segmentation allows each layer to remain relatively simple in its individual function while providing complex integrated capabilities when coupled together, reducing the complexity burden on any single component
