User-configurable fraud rules attached to a payment card
A system that lets an individual cardholder select fraud-detection rules that are stored in a database and applied to transactions made with their payment card. The rules include at least one rule that evaluates the validity of a single transaction; the system associates the card with the rule set and enforces those rules during authorization. Issuers or processors would use the system to let cardholders tighten or relax controls on their card activity.
(57) What the patent covered
This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.
The main independent claim covered a database record linking a transaction card to one or more fraud-detection rules (including a rule that assesses a single transaction) and a computerized interface that permits the cardholder to specify those rules governing access to the card's funds.
Distinguishing feature: Cardholder-directed selection and storage of per-card fraud rules that include single-transaction validity rules, stored and enforced by the issuer/processor.
Novelty 3/5. At filing (mid 2000s) real-time authorization systems and issuer-side rule engines were common; the novelty was empowering the individual cardholder to choose and store per-card fraud rules rather than having issuer-only control.
Implementation
Build a web/mobile portal that authenticates cardholders, writes selected rules into a rules database keyed by card token or PAN, and adds a rules-evaluation step in the authorization pipeline so each incoming authorization query is checked against the card's rule set and returned as approve/decline or challenge.
Components: Card identifier (PAN or token), rules database (issuer/processor store), web or mobile user interface for rule selection, authorization rule engine integrated with issuer/processor.
Buildability 5/5. The engineering effort is straightforward; the main work is integrating a rules-evaluation call into existing authorization flows and ensuring secure authentication and low-latency lookups.

Before manufacturing
No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.
Operational risks include latency and availability in authorization paths, user authentication and UX for non-technical cardholders, and potential regulatory or contractual restrictions with card networks; patent has lapsed so prior-right risk is lower but related patents may exist.
