Abstract: A method and system for performing a redemption transaction at a point-of sale terminal. The cardholder initiates the transaction using a redemption card. The terminal obtains a transaction amount, a private currency, and an exchange rate. The transaction amount is converted into a transaction amount miles equivalent using the exchange rate, and the transaction amount miles equivalent is compared against the balance of the redemption account associated with the redemption card. The terminal transmits a clearing record for further processing. The clearing record is received by a clearing server, which identifies a lodged card associated with the transaction. The clearing server computes a periodic aggregate amount comprising the aggregate transaction amount for all transactions associated with the lodged card and a particular merchant during that period. The clearing server triggers a single transaction towards an acquirer associated with the merchant for the periodic aggregate amount.
