JPMorgan Chase's newly granted patent describes a "cryptogram lockbox" designed to generate the one-time codes that authorize credit-card transactions locally — inside a merchant's data center or cloud — rather than requesting them from a payment network or card issuer, according to the patent. Fig. 1 shows the system architecture, with a customer interacting with merchant systems that contain the lockbox, which in turn connects to a financial institution. Irving-based Gayathri Sundar is among several inventors named on the patent. [Composite image: Sources, U.S. Patent No. 12619977, Fig. 1; DI Studio]
