DISPLAY PAYMENT CARD WITH FRAUD AND LOCATION DETECTION
First Claim
1. A method for limiting card-not-present payment card fraud, comprising:
- loading individual table values with a sequence of next valid values to crypto-tables within a population of payment cards during manufacturing and before distribution to their corresponding users;
equipping each said payment card with a user display, and a device to automatically fetch a next valid value in a sequence from said crypto-table to a dynamic portion of a new account number readable on said display each time such is used in a merchant transaction;
providing a financial network for reporting said new account number by a user to a merchant when initiating a card-not-present merchant transaction;
analyzing a report from said merchant to determine if said new account number includes an expected next valid value in said crypto-table that was loaded in that particular payment card during manufacturing and before distribution its user;
logging a merchant identification data associated with each said report from said merchant into a database; and
deciding whether to authorize said merchant transaction based on previous data logged into said database related to previous merchant transactions for said particular payment card.

Abstract
A payment card comprises a display to support card-not-present transactions where no card reader is available to automate the transaction, and an account number retrieval method for dynamic, one-time use virtual account numbers whose use can assist authorities in rapid fraud and location detection. The account number generator is able to produce a sequence of virtual account numbers over its life that are predictable by the issuing bank and useful in authenticating transactions. A server for the issuing bank logs the merchant locations associated with each use or attempted use, and provides real-time detection of fraudulent attempts to use a virtual account number outside the predicted set. Fraud identification efforts can then be directed in a timely and useful way.

5. A card-not-present payment card system, comprising:
-
a payment card with a display to communicate account information to a payment processing server through a merchant; a sequence of next valid values permanently disposed in crypto-tables within said payment card; a microcontroller included in said payment card to internally fetch a sequence of next valid values said crypto-table to include as a dynamic portion of a new account number for automatic presentation on said display and without user intervention each time the payment card is used in a merchant transaction; a payment processing server configured to analyze a report from said merchant to determine if said new account number includes an expected next valid value in said crypto-table that was loaded in that particular payment card during manufacturing and before distribution to its user; a database of merchant identification data associated with each said report from said merchant; and a program for deciding whether to authorize said merchant transaction based on a validity criteria associated with said new account number. wherein, the user is not provided an input to make choices or selections into their payment card, and the payment card itself does not employ a card number generator algorithm to calculate said new account number. - View Dependent Claims (6, 7, 8)

9. A display-type payment card for card-not-present financial transactions, comprising:
-
a user display on a payment card base; a crypto-table disposed in the payment card and including a set of individual table values having a sequence of next valid values loaded during manufacturing and before distribution to users, wherein the numbers stored in the table during manufacturing were already encrypted using a seed connected with the user, or chosen at random and then ordered, such that a next valid number cannot be predicted from any that were used before and that there is an expected order to the crypto-table values being fetched by each payment card; and a device to automatically fetch a next valid value in a sequence from said crypto-table to a dynamic portion of a new account number readable on said display during a merchant transaction. - View Dependent Claims (10, 11, 12, 13, 14, 15)
