E-Card NFC Interrogation Reporting for Fraud Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized transactions can occur with electronic NFC cards without the owner's awareness, leading to potential fraudulent 'ghost purchases' due to lack of real-time monitoring and authorization.
Innovation Solution
An apparatus and method that include a processor and computer-readable storage medium to receive NFC interrogation signals from POS assemblies, allowing for automatic reporting of transactions to a consumer electronics device, which can prompt the owner for authorization before completing transactions, using Bluetooth and NFC technologies for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic NFC transaction response is implemented, then transaction speed and convenience are improved, but security against unauthorized transactions deteriorates
Solution Approach 1:
The system performs preliminary actions by notifying the customer device of an attempted transaction before the e-card responds to the POS assembly. This advance notification allows the customer to authorize or block the transaction beforehand, preventing unauthorized transactions while maintaining automatic response capability.
Solution Approach 2:
The system implements feedback by continuously monitoring NFC interrogation signals and immediately notifying the customer device of transaction attempts. This real-time feedback loop enables the customer to control transaction authorization, balancing automatic response speed with security oversight.
2Reliability
If real-time transaction monitoring is added, then security against ghost purchases is improved, but device complexity increases
Solution Approach 1:
The system uses the customer's existing mobile device as an intermediary between the e-card and the POS assembly. This intermediary receives NFC interrogation signals, notifies the customer, and relays authorization decisions back to the e-card, adding security without requiring a completely new system architecture.
Solution Approach 2:
The customer device serves multiple functions: it acts as a notification receiver, authorization decision-maker, and communication bridge between the e-card and POS assembly. This multi-functionality reduces the need for separate dedicated security devices, minimizing added complexity.
3Reliability
If customer authorization is required before transaction completion, then security is improved, but transaction time increases
Solution Approach 1:
The system uses periodic action by implementing time-based authorization thresholds. For small transactions below a predetermined threshold, automatic authorization occurs without customer notification. For larger transactions, customer authorization is required. This periodic differentiation balances security with transaction speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security by alerting the card owner of potential fraudulent transactions and allowing for real-time authorization, thereby reducing unauthorized use and protecting against 'ghost purchases'.
Implementation Method 1
The card includes an NFC element that is responsive to an interrogation signal from the POS assembly by providing card data in response to the interrogation signal
Implementation Method 2
The card further includes a Bluetooth element that is responsive to the transaction notification by wirelessly communicating with the computing device
Data Source
AI summary
A bank customer's electronic debit or credit card (“e-card”) automatically reports to the customer's CE device the receipt of transaction interrogations the e-card receives from a point of sale (POS) apparatus. The e-card may simply report to the CE device and respond to the interrogation, or it may await a signal from the CE device prior to responding to the interrogation.
