Abstract
A cardless sales method and system for purchasing a commodity by transmitting card issuing information stored in a mobile communication terminal to a sales processing device and capable of promptly authenticating card information by the sales processing device alone and safely handling the card information. Card authentication information (35) issued from a card issuer (1) and card issuing information (34) including card information (33) are stored in a mobile communication terminal (7). Upon sales processing using the card issuing information (34), the card issuing information is transmitted from the mobile communication terminal (7) to a sales processing device (18) and the sales processing device (18) judges validity of the card information according to the card authentication information (35) contained in the card issuing information (34) received from the mobile communication terminal. When the card information (33) is judged to be valid, a predetermined sales processing is executed by the sales processing device (18).
