Abstract: After loss of communications between a cash handling device and a financial institution, transactions may continue to be processed. In one configuration, the transactions may be processed up to a predefined transaction limit. Transaction limits may be defined by a number of transactions, a dollar amount transacted or to be transacted, an amount of time and/or combinations thereof. Additionally or alternatively, the transaction limit may be specific to one or more types of transactions. Transaction data may be stored in memory until communication has been re-established, at which time the data may be transmitted to the financial institution for processing.
