Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face delays and security risks when their physical wallets are lost or stolen, as existing technologies lack efficient methods to detect missing cards and provide immediate replacement solutions, leading to disruptions in transaction capabilities.
Innovation Solution
A system that includes a microcontroller in the physical wallet to detect and communicate with RFID chips, EMV chips, and other payment instruments, allowing for real-time notification of missing cards and generation of replacement digital cards that can be used on mobile devices for secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical wallet is lost or stolen, then the user's data security is compromised, but the user experiences delays and disruptions in transaction capabilities until replacement cards are issued
Solution Approach 1:
The system performs preliminary actions by detecting missing cards in real-time and immediately generating replacement digital cards before the user even requests them. The microcontroller continuously monitors the physical wallet for missing cards and automatically initiates the replacement process, eliminating the traditional delay where users had to manually contact issuers after losing their wallets.
Solution Approach 2:
The patent introduces a digital card as an intermediary solution between the lost physical card and the replacement physical card. This digital card, stored on the user's mobile device, serves as a temporary substitute that maintains transaction capabilities while the permanent replacement is being prepared and mailed, thus bridging the time gap and preventing service disruption.
2Reliability
If traditional card replacement processes are used, then data security is maintained through authentication, but users face delays and potential unauthorized use during the replacement period
Solution Approach 1:
The system implements self-service by enabling the user to immediately activate and use a replacement digital card on their mobile device without waiting for the physical replacement card to arrive. The user can autonomously restore their transaction capabilities through the mobile application, eliminating the need to contact customer service or visit branches, thus maintaining both security and productivity.
Solution Approach 2:
The patent creates a digital copy of the card functionality that can be instantly deployed on the user's mobile device. This digital replica contains the necessary account information and authentication credentials, allowing the user to continue transactions immediately while the original physical card remains inactive or lost, thus maintaining productivity without compromising security.
3Ease of operation
If biometric data is stored digitally, then authentication convenience is improved, but the risk of permanent compromise increases if the data is stolen
Solution Approach 1:
The system segments the authentication process into multiple independent components: biometric data is stored separately from account data, and the digital card contains only necessary transaction information. This segmentation ensures that if one component is compromised, the others remain secure, reducing the impact of potential breaches while maintaining authentication convenience through the use of biometrics.

AI summary
Various systems, mediums, and methods may be implemented to provide data security by detecting microcontrollers in physical wallets. One example method may include detecting that a physical wallet comprises a plurality of physical cards based at least on a communication with a microcontroller of the physical wallet; comparing the plurality of physical cards with a plurality of digital cards of a digital wallet that corresponds the physical wallet; detecting at least one missing physical card from the physical wallet based at least on comparing the plurality of physical cards with the plurality of digital cards; and transmitting a notification to one or more user devices with access to the digital wallet. The notification may indicate information identifying the at least one missing physical card.
