Secure Payment Card System Using Magnetic Stripe and PIN Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional credit cards are insecure, as they can be used fraudulently if lost or stolen, and require multiple cards for different financial institutions, lacking visibility into account status and secure authentication methods for transactions.
Innovation Solution
A system comprising user hardware, a database manager, and payment processing space that allows secure storage and management of financial data, enabling real-time access and secure authentication for transactions using a magnetic stripe card or smart card, with features like PIN protection and secure communication via cellular networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If credit cards store visible account information for easy access, then ease of operation is improved, but security deteriorates due to fraudulent use
Solution Approach 1:
The patent extracts sensitive account information from the physical card itself. The magnetic stripe contains encoded account data that can be read by POS terminals, but the cardholder's name and other identifying information are not printed on the card face. This separation allows the card to function for transactions while reducing the risk of identity theft if the card is lost or stolen.
Solution Approach 2:
The patent uses magnetic encoding to create a digital copy of account information on the magnetic stripe. Instead of relying on visible printed information, the system transfers account data magnetically, which can be read electronically but is not visible to casual observers. This provides secure access while maintaining ease of use at POS terminals.
2Adaptability or versatility
If multiple cards are carried for different financial institutions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal payment card that can access multiple financial institution accounts. The magnetic stripe is programmed with account information from different banks and financial institutions, allowing the cardholder to use a single card for transactions at various institutions. This consolidates multiple cards into one while maintaining adaptability to different financial systems.
Solution Approach 2:
The patent combines multiple account functionalities into a single physical card. By encoding multiple account numbers and financial institution data on one magnetic stripe, the system merges the functionality of several separate cards into one unified device, reducing the number of cards the user must carry and manage.
3Productivity
If account information is stored on the card for quick access, then productivity is improved, but reliability deteriorates due to loss or theft
Solution Approach 1:
The patent applies different quality levels to different parts of the card system. The magnetic stripe contains essential transaction data for quick processing, while the card face deliberately omits sensitive identifying information. This local differentiation allows fast transactions where needed while maintaining security where information exposure would be harmful.
Solution Approach 2:
The patent pre-encodes account information on the magnetic stripe during card issuance, so that transaction data is ready for immediate use without requiring the user to manually input account numbers. This preliminary preparation enables quick transactions while the encoded data remains secure on the magnetic stripe rather than being visible on the card surface.
