Abstract: A computer-based method for communicating liability acceptance for payment card transactions is provided. The method uses a computer device including a processor and a memory. The method includes receiving, by the processor, a transaction authorization request message for a payment card transaction having a default-liable party. The transaction authorization request message includes a shifted-liability acceptance indicator identifying a different party to the transaction that accepts liability for the payment card transaction. The method also includes authorizing the payment card transaction based at least in part on the shifted-liability acceptance indicator. The shifted-liability acceptance indicator changes the liability for the payment card transaction from the default-liable party to the different party accepting liability.

Abstract: The present disclosure provides a description of systems and methods for verifying product authenticity at a point of sale through transaction messages. A point of sale may collect product identifiers from products that a consumer is interested in purchase as part of a traditional checkout process. Product identifiers can be included in special data elements in a transaction message that is submitted to a merchant's acquiring bank through for the payment transaction. As part of the processing of the transaction by the acquirer, the acquirer can consult a processor to check the authenticity of the products being purchased by examining a provenance blockchain for the product identifiers included in the transaction message. If the products are determined to be authentic, the transaction can proceed as normal. If the products are not authentic, then the acquirer can deny the transaction and stop the consumer from purchasing a counterfeit or fraudulent good.

A transfer process module hosted on the first interchange network receives a first service request from a requestor, formatted in accordance with a first set of proprietary communications standards associated with the first payment network, and transforms the first service request to a second service request formatted in accordance with a second set of proprietary communications standards associated with the second payment network. An enrichment services computer system hosted on the second interchange network receives the second service request and generates a first service response formatted in accordance with the first set of proprietary communications standards.

Abstract: A data update computing device is provided. The data update computing device receives, from one of a user computing device and a first relying party computing device, a first access authorization message, wherein the first access authorization message identifies (i) a first relying party and (ii) a first user data element of the user to be shared with the first relying party. The data update computing device generates a first globally unique identifier (GUID), wherein the first GUID is uniquely associated in a first record in a GUID database table with the first user data element and the first relying party; receives an updated value of the first user data element of the user; stores the updated value of the first user data element in the first record, and flag the first record as updated in the GUID database table; and transmits the first GUID to the first relying party.

Abstract: Methods and systems for providing cardholder authentication services on-behalf-of (OBO) issuers utilizing a payment card authorization network to bridge cardholder authentication and transaction authorization processes. In some embodiments, the process includes an OBO issuer service computer receiving an authentication message, storing the authentication message in a transaction database and then receiving a purchase transaction authorization request message from a payment network. The OBO issuer service computer then determines that an authentication value of the received purchase transaction authorization request message matches the authentication value of the stored authentication message, stores a record of the match, and transmits the purchase transaction authorization request to the payment network for purchase authorization processing.

Abstract: Methods and systems for processing booking transactions are provided. A server received a transaction request to book an asset for a time period. The transaction request comprises a token identifier assigned to the asset and data identifying the time period. The server then identifies token data associated with the asset based on the token identifier and determines availability of the asset during the time period based on the token data. If the asset is available for the duration of the time period, the server maps the token identifier to an account identifier and sends a request to credit an account identified by the account identifier to a server of an issuer of the account.

Abstract: A computer-implemented method includes registering at least a first merchant and a second merchant, the registering including a consent process for payment card network access. The registering enables a registered merchant to post equity financing auctions and to bid on posted equity financing auctions. When a posting for an equity finance request is received from a registered first merchant, a validated aggregate historical data for the registered first merchant can be obtained from the payment card network. When a bid, which includes an amount of finance offered and requested equity, is received on the equity finance request from a registered second merchant, a set of transaction data for the registered second merchant is obtained from the payment card network and a score is generated for the registered second merchant based on conditions in the equity finance request using the set of transaction data and the bid.
