  • Publication number: 20090192932
    Abstract: Disclosed are systems and methods for effecting international online financial transactions between individuals or between individuals and entities such as banks, merchants and other companies. In one embodiment, requests for international currency exchanges are processed in batch form. A currency accumulator may be used to keep track of currency exchange requests, where each currency is assigned a notional “bucket,” which is a symbolic representation of a database entry for the monetary amount which has been requested to be exchanged for a given currency. When the contents of a particular currency's “bucket” reaches a given level, the monetary amount in the bucket may be exchanged for an equivalent amount of a second currency.
