Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional financial instruments are easily stolen and fabricated, leading to widespread fraud and significant losses for individuals, organizations, and financial institutions, with existing anti-fraud methods being cumbersome, costly, and ineffective.
Innovation Solution
A computer system that manages financial transactions using geolocation data and short passcodes, eliminating the need for traditional financial instruments by associating user accounts with personal communication devices, and enhancing security with additional personal knowledge and challenge questions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional financial instruments (credit cards, debit cards, checks) are used for financial transactions, then ease of operation is improved, but reliability deteriorates due to easy theft and fabrication
Solution Approach 1:
The patent replaces traditional physical financial instruments with their digital counterparts stored in a database. Instead of using physical cards or checks that can be stolen, the system uses electronic records of financial instruments that exist only in digital form, eliminating the risk of physical theft while maintaining ease of transaction operation.
Solution Approach 2:
The patent substitutes the mechanical/physical system of traditional financial instruments (physical cards, checks, cash) with an electronic database system. Transactions are conducted by referencing digital records in a database rather than manipulating physical objects, thereby eliminating theft and fabrication risks associated with physical instruments.
2Ease of operation
If employee access to customer information databases is expanded for service purposes, then ease of operation is improved, but object-generated harmful factors worsen due to insider theft and fraud
Solution Approach 1:
The patent implements different access levels and permissions for different employees based on their specific job requirements. Instead of giving all employees universal access to customer information, each employee receives access only to the specific data and functions necessary for their role, reducing the risk of insider fraud while maintaining operational efficiency.
Solution Approach 2:
The patent incorporates audit trails and monitoring mechanisms that track employee access to customer information and transaction activities. This feedback system allows the organization to detect suspicious patterns, monitor for potential fraud, and hold employees accountable, thereby reducing insider threats while maintaining necessary access for service delivery.
3Reliability
If comprehensive verification procedures are implemented to detect fraud, then reliability is improved, but device complexity and loss of time worsen
Solution Approach 1:
The patent performs fraud detection checks in advance before transactions are completed. By verifying customer identity, validating financial instrument authenticity, and checking for suspicious patterns prior to authorizing transactions, the system prevents fraudulent transactions rather than detecting them afterward, reducing the need for complex post-transaction verification procedures.
Solution Approach 2:
The patent implements automated fraud detection algorithms and validation procedures that operate without human intervention. The system automatically verifies customer information, checks against fraud databases, and validates transaction patterns, eliminating the need for manual verification procedures and reducing complexity while maintaining high reliability.
4Ease of manufacture
If traditional mailing processes are used to distribute financial instruments, then ease of manufacture is improved, but object-generated harmful factors worsen due to theft during mailing
Solution Approach 1:
The patent replaces physical distribution of financial instruments through mailing with electronic distribution of digital records. Instead of printing and mailing physical cards or checks that can be stolen during transit, the system creates and distributes electronic copies stored in a secure database, accessible to customers through authorized interfaces, eliminating mailing-related theft risks.
Solution Approach 2:
The patent substitutes the physical mailing system with an electronic distribution system. Financial instruments are delivered digitally through secure electronic channels rather than through physical postal services, eliminating the vulnerabilities associated with physical transport while maintaining ease of instrument creation and distribution.

AI summary
A method for conducting a transaction with a consumer device includes receiving user input selecting a store as a party to the transaction with a consumer associated with the consumer device. The method also includes transmitting, to the account computer system, first identification information of the store and second identification information of the consumer device. The method further includes receiving, from the account computer system, a passcode based on transmitting the first identification information of the store. The method also includes receiving, from the account computer system, a payment amount due. The method still further includes transmitting the passcode to the store to finalize the transaction.
