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 verification system is provided that can enable tracking of online advertisements with successful sales of goods or services. The system can receive an advertisement tag as part of a request by a user relating to the product or service, the advertisement tag comprising an identity of a publisher of an advertisement regarding a product or service offered by a vendor, the publisher being different from the vendor; determine a contribution of the publisher's advertisement to the request; and update a set of transaction data structures in an electronic record to associate the identified publisher and contribution with the request.

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: A system allows for conducting the financial and commercial (buying, selling, donating, gifting and paying) transactions that leverage communication devices to avoid the disclosure of a user's payment information. The payee (seller, seller's agent, receiver of funds, etc.) provides information or a token to the payer (buyer, buyer's agent, or any other provider of funds) who then directs funds to that token. In other words, rather than the payer providing information that is used by the payee to “pull” funds from the payer, the system allows a payee to provide information to which a payer “pushes” a payment. Since the payment is “pushed” by a customer, and often, but not always, using some type of a communication and/or computing device, the point-of-sale (POS) terminal has essentially been transferred from the merchant to the customer.

Abstract: A multi-mode receiver includes a channel decomposition module (e.g., a Rake receiver) for separating a received signal into multipath components, an interference selector for selecting interfering paths and subchannels, a synthesizer for synthesizing interference signals from selected sub channel symbol estimates, and an interference canceller for cancelling selected interference in the received signal. At least one of the channel decomposition module, the synthesizer, and the interference canceller are configurable for processing multi-mode signals.

Abstract: A receiver includes a first finger that receives a non-interference-cancelled signal and output first demodulated data, a first phase estimate, and a first PN code. The receiver also includes a second finger that selectively receives the non-interference-cancelled signal and a first interference-cancelled signal generated from the non-interference-cancelled signal based on the first phase estimate and the first PN code. The second finger also outputs second demodulated data.

Abstract: The present invention provides systems and methods for parallel interference suppression. In one embodiment of the invention, a processing engine is used to substantially cancel a plurality of interfering signals within a received signal. The processing engine includes a plurality of matrix generators that are used to generate matrices, each matrix comprising elements of a unique interfering signal selected for cancellation. The processing engine also includes one or more processors that use the matrices to generate cancellation operators. A plurality of applicators applies the cancellation operators to parallel but not necessarily unique input signals to substantially cancel the interfering signals from the input signals. These input signals may include received signals, interference cancelled signals and/or PN codes.
