Abstract
Transaction processing in an offline environment for a prepaid product comprising a portable consumer device includes responding to presentation of the prepaid product at a reader for offline processing by initiating operation of the prepaid product, receiving data from the prepaid product at the reader that indicates the prepaid product is associated with a prepaid account balance, determining that the prepaid product is in a negative balance condition, and taking preventive action in response to the negative balance condition such that future acceptance of the prepaid product at a reader is prevented.
