A portable consumer device may have money stored therein, which can be calculated using an accumulator record and an exception record. The accumulator record can be incremented by the amount of any initiated transaction using the portable consumer device. The exception record can be incremented by the amount of any completed transaction using the portable consumer device. The portable consumer device may also have a limit amount, to record the amount of money added. The records allow for a later reconstruction of the device history, and can account for any errors or problems during transactions.
