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.
Claims15
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.
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.
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.
