摘要
PURPOSE: A card terminal equipped with a pre/post-payment function using an SAM(Secure Application Module) and a method for pre/post-payment of the same are provided to add a new settlement function without modifying a current card offering a specified settlement service and implement an encryption/verification function for the added settlement service at a low expense. CONSTITUTION: A card interface(120) transmits/receives data between cards. A pre/post-payment common SAM(113) offers a secure key commonly used for prepayment and post-payment. A settlement processor(110) performs pre or post-payment operation by using the pre/post-payment common SAM depending on a settlement mode selected from a subscriber. A transaction particulars storing part(115) stores settlement particulars.
