Abstract: The invention includes systems and methods for facilitating risk assessment for point of sale transactions utilizing at least one risk triggering value (RTV) stored within a distributed (e.g., local and/or regional) processing site. An RTV is a condensed version of a set of complex risk data and strategies usually found in central processing sites. The distributed site, after receiving a request for payment authorization, a risk value is calculated for the request. The distributed processing site compares the risk value to the RTV to determine whether to authorize payment. If the risk value is less than or equal to the RTV, the payment is authorized while a risk value greater than the RTV will not be authorized. After one or more authorizations, the distributed processing site forwards the information from the transaction(s) to the central site, wherein the central site calculates a new RTV for the account and distributes the new RTV to the distributed processing site.

Abstract: In a packet-based transaction processing system, workload is balanced across multiple computer systems. A plurality of packets is received from a plurality of clients over a plurality of communications sessions. Each of the plurality of packets includes a portion of a transaction involving a financial transaction instrument that requires authorization. The plurality of packets are processed to assemble a plurality of transactions. Each of the plurality of transactions is then transmitted to an application server selected from a plurality of servers that provides authorization for the transactions. The server may be selected from the plurality of servers based on a round-robin distribution of the plurality of servers, and additionally, the round-robin distribution may be modified to account for a workload on each of the plurality of servers.
