Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic transaction devices lack a user-friendly method for selecting and authorizing multiple accounts, and they often require additional equipment or complex training for operation, leading to increased downtime and costs.
Innovation Solution
A compact, durable device with a scroll wheel for account selection and multiple buttons for user verification and authorization, incorporating a memory for storing account information, digital user identification, and an LCD/LED screen for displaying options, which can connect via direct or wireless means to a checkout register, including a docking mechanism for data transmission and two-factor authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing electronic transaction devices store multiple account information, then account accessibility is improved, but the device complexity increases due to lack of user-friendly selection methods
Solution Approach 1:
The device enables self-service account selection through intuitive mechanical controls (scroll wheel and buttons) that allow users to independently navigate and select from multiple stored accounts without requiring complex interfaces or additional equipment, thereby improving account accessibility while keeping the device simple
Solution Approach 2:
The patent uses a simplified mechanical interface (scroll wheel and buttons) as a copy or abstraction of more complex electronic selection mechanisms, providing the same functional capability (account selection) through a simpler, more user-friendly interface that reduces perceived device complexity
2Adaptability or versatility
If additional equipment is required for device operation, then functionality is improved, but downtime and operating costs increase
Solution Approach 1:
The device integrates multiple functions (account storage, selection, verification, and authorization) into a single self-contained unit with a durable housing, eliminating the need for additional equipment and reducing downtime by ensuring all functions are available whenever the device is in use
Solution Approach 2:
The device performs self-verification through built-in digital signature and image transmission capabilities, eliminating the need for external verification equipment and reducing operating costs while maintaining full functionality
3Ease of operation
If traditional payment methods are used, then ease of operation is maintained, but security and fraud prevention are insufficient
Solution Approach 1:
The patent creates a digital copy of the user's signature and physical appearance (image) that can be transmitted and verified electronically, providing security comparable to traditional methods while maintaining ease of operation through automatic digital verification instead of manual processes
Solution Approach 2:
The patent replaces manual mechanical verification processes with automated digital verification using transmitted images and digital signatures, enhancing security while maintaining user-friendly operation through automatic authentication without requiring physical presence or manual verification
Data Source
AI summary
A system including a device having a screen and a memory to hold card data necessary to complete POS/ATM transactions. The device has an authorization, signature, PIN button and scroll wheel. Branding areas allow distributors to leverage space on the device. When the merchandise has been processed and ready to be paid for, the device holder either places their device in a docking station or holds it in front of a contact less reader. When the merchant is ready for authorization, the holder presses transmits the data to a register so the merchant can send the data through the card network for authorization. Once the transaction is authorized, the merchant requests the signature, fingerprint, and/or photo of the holder, which can be displayed, on the register to authenticate the holder. Upon completion, the transaction information is transmitted back to the device for storage and retrieval at a later date.
