Auto-sequencing Payment Card with Dynamic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional credit and debit cards are vulnerable to fraud in card-not-present transactions due to the static nature of personal account numbers (PAN), card verification values (CVV), and expiration dates, which can be easily copied, and existing security measures are inadequate for preventing unauthorized use.
Innovation Solution
A payment card with a store of issuer-defined pre-generated cryptograms that auto-sequence and display unique PAN, CVV, and/or EXP fields, allowing for use-once combinations without requiring changes in user behavior or infrastructure, using an on-board electronic display and auto-sequencer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static PAN, CVV, and expiration date are used on conventional cards, then card-not-present transactions can be processed easily, but fraud vulnerability increases significantly
Solution Approach 1:
The patent implements dynamic PAN, CVV, and expiration date fields that automatically change for each transaction or time period. The card contains multiple sets of these fields that are sequentially activated, transforming the static data into dynamic, time-varying information that cannot be reused by fraudsters
Solution Approach 2:
The card is pre-loaded with multiple sets of PAN, CVV, and expiration date fields during manufacturing. These fields are prepared in advance and automatically sequenced without requiring user intervention, enabling the card to provide fresh data for each transaction before fraud can occur
2Reliability
If dynamic magnetic stripes are implemented, then security is improved for card-present transactions, but card-not-present transactions remain vulnerable
Solution Approach 1:
The patent creates a universal solution that works for both card-present and card-not-present transactions. The dynamic field generation mechanism operates independently of the transaction type, providing security benefits in both scenarios without requiring separate systems or infrastructure changes
3Reliability
If token devices are used to generate one-time passwords, then security is enhanced, but infrastructure complexity and device requirements increase
Solution Approach 1:
The patent merges the security functionality previously requiring separate token devices directly into the payment card itself. The card contains integrated circuits that generate and display dynamic PAN, CVV, and expiration date fields, combining what were previously separate security mechanisms into a single unified device
Solution Approach 2:
The card autonomously generates and manages its own dynamic security fields without requiring external token devices or additional infrastructure. The card self-manages the sequencing and display of multiple field sets, eliminating dependency on separate security systems
4Reliability
If multiple field sets are stored on the card, then fraud resistance improves, but card data management complexity increases
Solution Approach 1:
The card contains an integrated sequencer that automatically manages the multiple field sets stored on the card. The sequencer autonomously tracks which fields have been used and automatically activates the next set in the sequence without requiring user intervention or complex external management systems

AI summary
A payment card comprises a store of issuer-defined pre-generated cryptograms that are loaded only once into the Card by a perso-bureau or issuer. An on-board and autonomous electronic display of the personal account number (PAN), card verification value (CVV), or expiration date (EXP) is auto-sequenced through the stored cryptograms. Each value displayed to the user is unique, and useful in a financial transaction only once. The Card thus requires no changes in behavior on the part of the User, because the existing merchant infrastructure is already equipped to collect PAN+CVV+EXP data for user verification and transaction authorization.
