Abstract: Implementations described herein relate to systems, methods and computer-readable media to provide high availability computer architectures for performing real-time authorization of transactions. In some implementations, the method includes receiving, at two or more groups of authorization control pods, transaction information about the transaction from a payment network, wherein each authorization control pod includes a processing service, a database service, and a policy agent; processing, at a corresponding policy agent of a single authorization control pod of the two or more groups of the authorization control pods, the transaction information by comparing one or more transaction attributes in the transaction information combined with contextual and historic data against one or more policies stored in the database service; and based on the comparison, transmitting one of an approval or a rejection of the transaction to the payment network.

Abstract: Implementations described herein relate to dynamic and predictive updating of a payment attribute of a payment instrument. In some implementations, the method includes receiving, at a computing device, route data for a plurality of trips, receiving, at the computing device, first trip data for the first trip from the user device, wherein the first trip data includes at least location data of the user device, calculating, based on the received first trip data, a fuel likelihood score for the first trip, comparing the fuel likelihood score to a first threshold, based on a determination that the fuel likelihood score meets the first threshold: transmitting, to a computer associated with a payment network, a message to update one or more payment attributes stored at the payment network and associated with the first payment instrument, and displaying an indication that the first payment instrument is approved for the fuel transaction.

Abstract: A transaction management service and method are disclosed that can streamline transaction tracking and budget management. Transactions may be pre-approved based on inheritance and/or context-based authorization. The system can integrate a payment method, transaction tracking service, and a budget allocation service, among other operations.

Abstract: The present disclosure describes one embodiment of an operating center server for managing communication sessions between terminal devices such as mobile phones, VOIP phones, and computers for example. The OC server creates and maintains sessions for one or more terminal devices that allow communication between these disparate devices on disparate communication networks through the OC server.
