A first method comprises receiving at a computer apparatus an authorization request message comprising a first merchant identifier. The request message may also comprise an account identifier associated with an account and a first transaction amount for a first transaction conducted with a first merchant. The first method further comprises determining, by the computer apparatus, if an account comprises merchant specific currency associated with the first merchant that may be used to conduct the first transaction. It may then be determined if there is sufficient merchant specific currency associated with the first merchant in the account to pay for the first transaction amount. If there is insufficient merchant specific currency associated with the first merchant to pay for the first transaction amount, then non-specific currency in the account is applied automatically to a remainder of the first transaction amount. |
