Secure Transaction Card Data Presentation via NFC Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of transaction cards has led to increased fraud due to the embossing of card data on their surfaces, making blank or numberless cards less appealing due to the lack of a secure and quick method for cardholders to access their data for online transactions.
Innovation Solution
A method and system that securely presents transaction card data on a user device by pairing the card with the device via near-field communication, using a generated pairing identifier, and validating the pairing to temporarily display the data on the device without storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transaction card data is embossed or printed on the external surface of the card, then cardholders can easily access their data for online transactions, but this enables unscrupulous elements to surreptitiously read the data and engage in fraudulent transactions
Solution Approach 1:
The patent extracts the transaction card data from the physical card surface by issuing blank or numberless cards. The card data is stored electronically in a database associated with the card issuer, and can be temporarily displayed on authorized user devices through secure authentication, eliminating the need for embossed or printed data on the card itself.
Solution Approach 2:
The patent introduces an intermediary system consisting of a secure database and authentication mechanism between the card and the card data. This intermediary allows authorized access to card data through authenticated user devices while preventing unauthorized reading, thus resolving the contradiction between ease of access and fraud prevention.
2Object-affected harmful factors
If blank or numberless transaction cards are issued to mitigate fraud, then security is improved, but cardholders lack a quick and secure method to access their card data for online transactions
Solution Approach 1:
The patent implements preliminary action by pre-establishing secure authentication credentials and pairing mechanisms between the blank card and authorized user devices. The system prepares secure access pathways in advance through device pairing and authentication setup, enabling cardholders to quickly and securely access their card data when needed without compromising security.
3Ease of operation
If transaction card data is stored locally on a mobile application for quick access, then ease of operation is improved, but data security risk increases
Solution Approach 1:
The patent uses copying by temporarily displaying card data on authorized user devices rather than storing it locally in the mobile application. The system creates transient copies of the card data that are displayed only when needed and automatically deleted afterward, eliminating the security risk of local storage while maintaining quick access capability.
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
This solution enhances security and convenience for cardholders, reducing fraud risks and increasing adoption of blank or numberless cards by enabling quick and secure access to transaction data while preventing unauthorized storage.
Implementation Method 1
pairing the card with the device via near-field communication
Data Source
AI summary
A method for securely presenting transaction card data of a transaction card includes receiving, by a server, a pairing request to pair the transaction card with a user device. Based on the pairing request, the transaction card is paired with the user device by way of a pairing identifier. The server receives, from the user device, a data presentation request to present the transaction card data on the user device. In response to the data presentation request, the server validates the pairing between the user device and the transaction card based on the pairing identifier. The server communicates, to the user device, the transaction card data based on the validation of the pairing between the user device and the transaction card. The communicated transaction card data is presented on a user interface rendered on the user device.
