The present invention is related to a card transaction settlement method of a point of sale system, POS system, and more particularly to the card transaction settlement method in which a payment by either the credit card or the debit card is made after an approval before the card transaction for the virtual transaction amount is given, and in which when the transaction is completed, an approval after the card transaction for the actual transaction amount is requested for the transaction settlement whereby the settlement with the cards can be conveniently accomplished since conflict between the merchant and the consumer, caused by such as the difference between the transaction amount and the debited amount against the card, can be eliminated, and whereby the merchant has less of the financial risk for refund, and whereby the signature is not necessary in the signature form, resulting in that true non- cashier self- service sales can be introduced to the sales management system.
