Abstract
A method for processing a transaction using a dynamic PAN (Primary Account Number), performed by a payment device that provides a card reader with ISO (International Standardization Organization) standards of track 2 information. A PAN area of the track 2 information is divided into a first area, in which a BIN (Bank Information Number) is included, and a second area, in which the BIN is not included. A dynamic area is formed by encrypting the second area and a dynamic PAN area is formed by combining the first area with the dynamic area. Track 2 information (which includes the dynamic PAN area) is provided to the card reader.
