Exclusive Wireless Bonding for Mobile Payment Readers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional payment terminals are not suitable for mobile businesses like taxis and food trucks, as they require a fixed location and wired connections, leading to difficulties in managing wireless connections between payment readers and multiple mobile devices.
Innovation Solution
Implementing a payment system where a payment reader establishes an exclusive bond with a single mobile device using Bluetooth low energy (BLE) for secure and efficient transaction processing, allowing users to switch bonds between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple payment readers and mobile devices are located within the same area to support mobile businesses, then the system becomes more adaptable to mobile transactions, but it becomes difficult to determine which payment devices should communicate with which payment readers
Solution Approach 1:
The patent segments the wireless communication environment by creating exclusive bonding relationships between payment readers and mobile devices. Each bonding relationship forms an isolated communication channel, dividing the complex multi-device environment into manageable one-to-one connections. This segmentation resolves the contradiction by maintaining adaptability through multiple independent bondings while simplifying connection management through exclusive pairings.
Solution Approach 2:
The patent introduces bonding information as an intermediary mechanism that mediates communication between payment readers and mobile devices. The bonding information stored in memory acts as a mediator that identifies which devices are authorized to communicate, eliminating the need for complex real-time discovery and pairing protocols. This intermediary approach enables adaptable multi-device support while simplifying connection management through pre-established relationships.
2Reliability
If a payment reader establishes exclusive bonding with a single mobile device, then connection security and reliability are improved, but the ability to serve multiple devices simultaneously is reduced
Solution Approach 1:
The patent applies dynamics by allowing the bonding relationships to be flexible and changeable over time. The payment reader can establish exclusive bonding with one mobile device at a time, but can break and re-establish bonds with different devices as needed. This dynamic approach resolves the contradiction by maintaining connection reliability through exclusive bonding while preserving multi-device support capability through the ability to dynamically change bonding partners.
Solution Approach 2:
The patent uses preliminary action by pre-establishing bonding relationships between payment readers and mobile devices before transactions occur. The bonding information is stored in memory in advance, creating pre-authenticated communication channels. This preliminary bonding resolves the contradiction by ensuring connection reliability through pre-established secure links while enabling multi-device support through multiple pre-configured bonding relationships that can be activated as needed.

AI summary
A first device and a second device may establish wireless pairing, and based on that wireless pairing, establish wireless bonding. During the wireless bonding, the two devices may have multiple connections during which information is exchanged. One of the devices may also attempt to pair with a third device. The wireless bond between the first device and the second device may be broken, and a wireless bond may then be formed with the third device.
