Solution Overview

Problem

Conventional peer-to-peer transfer systems are time-consuming and prone to user errors due to the manual entry of user identifiers, requiring significant computational resources and often resulting in incorrect transfers without guaranteed returns.

Innovation Solution

An application programming interface (API) is integrated with merchant applications and payment service systems to facilitate split bill payments and purchase transfers, utilizing Bluetooth Low Energy connections and geo-fencing to automatically identify bill payers or recipients, and enable seamless transactions through a payment service system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual entry of user identifiers is used in conventional transfer systems, then transfers can be initiated, but the process becomes time-consuming and prone to user errors

Engineering Contradiction:
Improvetransfer accuracyVSAvoidtransfer initiation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical entry of user identifiers with automated electronic identification systems. Specifically, it uses Bluetooth Low Energy (BLE) technology to automatically detect and identify receiving devices, and geo-fencing technology to determine user location and identity based on geographic boundaries. This substitution eliminates the need for manual typing of usernames, email addresses, or phone numbers, thereby reducing both time consumption and error rates in transfer initiation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service identification where the receiving user's device automatically provides its identifier information to the transfer system without requiring the transferring user to manually input it. The BLE technology allows the receiving device to broadcast its identifier, and the transferring device can automatically capture this information. Similarly, geo-fencing automatically identifies users within specific geographic areas, allowing the system to self-determine the correct recipient without manual intervention.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If manual entry interfaces are provided to facilitate transfers, then users can initiate transfers, but significant computational resources are required and user errors increase

Engineering Contradiction:
Improvetransfer initiation easeVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex manual entry interfaces with automated electronic identification systems. Instead of presenting users with forms requiring entry of usernames, email addresses, or phone numbers, the system uses BLE technology to automatically detect nearby devices and geo-fencing to automatically identify users within geographic boundaries. This substitution simplifies the user interface to minimal actions (such as selecting from auto-detected recipients) while reducing the computational burden of processing and validating manually entered data.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces intermediary technologies between the transferring user and the transfer system. BLE actuators and geo-fencing boundaries act as intermediaries that automatically perform the identification function. The BLE technology serves as an intermediary layer that broadcasts and captures device identifiers automatically, while geo-fencing acts as an intermediary geographic boundary system that automatically determines user identity based on location. These intermediaries handle the complexity of identification, leaving the user interface simple and intuitive.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A payment service system may receive a request to complete a first purchase of at least one ticket for an event, wherein the at least one ticket is offered for sale by an event organizer to a customer. The payment service system may send the at least one ticket to the application on a first mobile device of the customer, receive a request via the application to transfer ownership of the at least one ticket to a new customer, and receive an indication, from a corresponding application on a second mobile device of the new customer, to acquire the ownership of the at least one ticket. Based on the indication, the payment service system may process an electronic payment for the transfer of the ownership and transfer the at least one ticket from the application on the first mobile device to the corresponding application on the second mobile device.
