  • Publication number: 20250045374
    Abstract: Disclosed are various approaches for relationship and attribute management are described. In some examples, a verifier service performs a verification process using a relationship decentralized identifier (DID) that provides proof of a relationship between the holder and a DID management service. An attribute request is that specifies an attribute is transmitted from the verifier service to the DID management service. The DID management service provides the verifier service with information based on the attribute once the holder provides an authorization response that authorizes usage of the attribute.

  • Patent number: 12154101
    Abstract: Systems and methods for voice-enabled transactions are disclosed. A merchant system may generate a transaction request comprising a transaction amount and a merchant identifier. The merchant system may invoke an audio signal generator to generate an audio transaction signal comprising the transaction request data. A voice assistant may play the audio transaction signal. The user initiating the transaction may use a mobile device to detect and ingest the audio transaction signal. In response to detecting and ingesting the audio transaction signal, the mobile device may interact with a payment network to authorize, process, and complete the transaction request. The payment network may transmit a transaction approval to the merchant system.

  • Publication number: 20220391896
    Abstract: Disclosed are various embodiments for a hosted point-of-sale service that provides the security features of card-present transactions for card-not-present transactions. The various embodiments of the present disclosure can be configured to receive a merchant identifier and a transaction amount for a transaction from a merchant terminal, as well as receive the merchant identifier and encrypted payment account data for the transaction. The encrypted payment account data can then be decrypted. An authorization request for the transaction is then generated based at least in part on the merchant identifier, the transaction amount, and the payment account data. The authorization request is then sent to a payment processor, which can route the authorization request to an authorizing entity via a payment network. An authorization response is received in response from the authorizing entity via the payment processor, and the contents are forwarded on to the merchant terminal.
