Abstract
A system and method for confirming transactions is provided. A central processor receives a request to process a current transaction coupled with prior transaction information corresponding to a prior transaction. In response to receiving a prior transaction identifier, the central processor determines whether the prior transaction and the first transaction are identical based on the prior transaction information. If the prior transaction is determined to be different from the first transaction, the central processor amends a first transaction record to indicate that the first transaction is a questionable transaction.
