Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical connection is used between the reader and computing device, then data transmission security is improved, but convenience and flexibility deteriorate
Solution Approach 1:
The patent replaces the mechanical physical connection system with a wireless communication system. The reader communicates with the mobile device via Bluetooth or Wi-Fi, eliminating the need for physical cables or ports while maintaining secure data transmission through encrypted wireless protocols.
2Ease of operation
If wireless communication protocols are used, then convenience and flexibility are improved, but data transmission security may deteriorate
Solution Approach 1:
The patent changes the security parameters of wireless communication by implementing encrypted data transmission channels. The system uses security protocols to encrypt payment card data and user identifying information before transmission, ensuring that wireless communication maintains the same security level as physical connections.
3Adaptability or versatility
If multiple wireless communication protocols are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The reader is designed with multi-functionality to support multiple wireless communication protocols (Bluetooth and Wi-Fi). This allows the device to adapt to different mobile devices and communication environments while maintaining a unified interface for payment card reading and data processing.
Data Source
AI summary
A wireless device including a reader to read information from a payment card and generate data. A verification module verifies whether the reader has correctly read the information. A security module securely connects the wireless device to a mobile device using a first or a second wireless communication protocol. A transmitter transmits the data and identifying information received from a user to the mobile device using the first or the second wireless communication protocol. The mobile device transmits the data and the identifying information to a payment system. A receiver at the wireless device receives from the mobile device an acknowledgement received by the mobile device from the payment system, indicating whether the payment system has approved the data and the identifying information. An indicator on the wireless device indicates whether the reader has correctly read the information and the payment system has approved the data and the identifying information.
