Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile card readers require cumbersome and time-consuming user interaction for pairing with computing devices, and existing systems may expose transaction data to third-party interception during the pairing process.
Innovation Solution
A mobile card reader that pairs automatically with a computing device via a physical connector, using data exchanged through the connector to establish a secure wireless communication link without user intervention, utilizing technologies like Bluetooth LE, Near Field Communication, or Wi-Fi, and encrypting data to prevent third-party access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pairing methods are used, then device connectivity is achieved, but user interaction time and complexity increase
Solution Approach 1:
The card reader performs preliminary actions by automatically initiating the pairing process when connected to the computing device. The system pre-configures wireless communication settings and automatically establishes a connection without waiting for user input, thereby eliminating pairing time and complexity.
Solution Approach 2:
The card reader implements self-service pairing by autonomously detecting the computing device, selecting appropriate wireless protocols, and establishing connections without user intervention. The system manages its own pairing process, removing the burden of manual user interaction.
2Adaptability or versatility
If wireless communication is enabled, then connectivity flexibility is improved, but data exposure to third parties increases
Solution Approach 1:
The patent introduces an intermediary security layer through encrypted wireless communication channels. The encryption protocol acts as a mediator between the card reader and computing device, allowing flexible wireless connectivity while preventing third-party interception of data transmitted between devices.
Solution Approach 2:
The system employs temporary, single-use encryption keys and session tokens that are discarded after use. This approach provides secure communication flexibility while minimizing data exposure risks, as intercepted data from temporary credentials would be useless to attackers.
