Abstract: The present invention relates to a system and a method for recognizing a credit card number and expiration date by using a terminal device. The method for recognizing a credit card number and expiration date comprises the steps of: (a) acquiring a card image through a camera of a terminal device; (b) detecting the position of a card number and recognizing numbers of the card number from the acquired image; and (c) detecting the position of expiration date and recognizing numbers of the expiration date from the acquired image. Therefore, recognition rate can be improved compared to an image processing based technique.
