Innovation Solution
A flexible card with a transaction display, comprising a card body, a flexible electric control mechanism, a flexible display unit, and a light emitting unit, where the flexible electric control mechanism includes a circuit carrier board with a transaction processing mechanism, a graphics layer, and a light emitting unit, providing enhanced structural stability, reliability, and transaction security through output prompts during transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional display-type cards are used, then basic card functionality is provided, but security verification mechanisms and transaction display mechanisms are lacking, exposing data to theft risks
Solution Approach 1:
The patent combines multiple functions into a single flexible card device: transaction processing mechanism, display unit, light emitting unit, and sensor unit are all integrated into one card body. This merging approach enhances security by incorporating verification mechanisms while maintaining a compact card form factor, resolving the contradiction between improved security and device complexity.
Solution Approach 2:
The flexible card serves multiple functions simultaneously: it processes transactions, displays transaction information, provides visual feedback through light emitting units, and detects card insertion/removal events. This multi-functionality allows the card to improve security and user awareness without requiring multiple separate devices, thus managing complexity while enhancing reliability.
2Reliability
If no transaction display mechanism is provided, then card structure remains simple, but transaction data is exposed to theft risks and user awareness is reduced
Solution Approach 1:
The display unit acts as an intermediary between the transaction processing mechanism and the user. It visually presents transaction information on the card itself, allowing users to verify transactions without exposing sensitive data externally. This intermediary approach protects data while enhancing user awareness, resolving the contradiction between data protection and display complexity.
3Reliability
If multiple functional units are integrated into the flexible card, then transaction security and user awareness are enhanced, but structural complexity increases
Solution Approach 1:
The patent uses a flexible card body that can accommodate multiple functional units (transaction processing mechanism, display unit, light emitting unit, sensor unit) within a thin, flexible structure. This flexible shell approach allows integration of complex functionality while maintaining a simple, card-like form factor, resolving the contradiction between enhanced security and structural complexity.

AI summary
A flexible card having a transaction display is introduced. The flexible card includes a card body, a flexible electric control mechanism, a flexible display unit and a light emitting unit. The flexible card body includes a first plate and a second plate combined with each other. The flexible electric control mechanism is disposed between the first plate and the second plate and includes a circuit carrier board and transaction processing mechanism. The flexible display unit is disposed on the circuit carrier board and is electrically connected to the transaction processing mechanism. Thus, the flexible electric control mechanism can be stably combined in the flexible card body to improve structural stability and reliability. During use, the transaction processing mechanism performs a transaction with a payment apparatus, and the flexible display unit and the light emitting unit output transaction information, achieving enhanced transaction security and convenience.
