  • Publication number: 20250071549
    Abstract: Disclosed are example methods, systems, and devices that allow for the generation and provisioning of digital credentials, which may demonstrate that a trusted entity has validated individual identity attributes, or sets of attributes, of a user. Digital credentials may also demonstrate one or more extrapolations resulting from deductions or inductions from validated identity attributes. A receiver device may indicate which identity attributes or extrapolations are sought by displaying a QR or other code and/or via a transmission using NFC or other wireless communication, and a user device may access corresponding digital attributes in an ID wallet to be provisioned via code or transmission. Digital credentials may restrict uses and usability of identity attributes. Cryptographic keys and/or distributed ledger records may allow recipients to verify authenticity of digital credentials. The same identity attribute may be proven by showing validation by multiple selectable trusted entities.

  • Patent number: 12198138
    Abstract: Systems, methods and computer-readable storage media utilized to complete a cardless transaction on a distributed ledger network. One method includes receiving, by a point-of-sale (POS) computing device, a transaction request including a biometric sample from an individual associated with a payment account at a financial institution. The method further includes authenticating, by the POS computing device, the biometric sample by cross-referencing the biometric sample with a biometric dataset stored on the distributed ledger network. The method further includes, in response to authenticating the biometric sample, generating, by the POS computing device, a cryptogram associated with the biometric sample and processing, by the POS computing device, the transaction request utilizing the cryptogram.
