SYSTEM FOR PROVIDING LOTTERY BY USING IC CHIP

摘要

PURPOSE: A lottery providing system using IC chips is provided to increase users' interest by providing the new service in which card usage and lottery are combined to the card users. CONSTITUTION: When a client pays with the credit card, a terminal(105) of a membership store stores the numbers which the client selects in the storage area of the IC chip of the client. When the number already exists, the terminal of the membership store connects/stores the new number data to the stored number data. A server(110) determines whether the number is winning lottery numbers or not.
