The present invention relates to processing of credit card transactions where conversion to the cardholder currency is securely and efficiently processed at a point of sale apparatus or at a merchant site into a cardholder currency. The number of currency exchanges is reduced thereby benefiting cardholders and eliminating merchant foreign exchange exposure. Competitive merchant service charges (MCS) are also possible in addition to enhancing the trust and confidence of cardholders.
