TERMINAL, SERVICE PROVISION APPARATUS, AND COUPON SERVER, ELECTRONIC WALLET SYSTEM HAVING SAME, CONTROL METHOD THEREOF, AND RECORDING MEDIUM IN WHICH COMPUTER PROGRAM IS RECORDED

摘要

Disclosed are a terminal, a service provision apparatus, and a coupon server, an electronic wallet system including the same, a control method thereof, and a recording medium in which a computer program is recorded. That is, the present invention searches for information (or search-type coupon information) on a coupon relating to a keyword designated by a client from among coupons registered by an affiliated company in real-time and provides the searched coupon information to a terminal, instead of designating and issuing, one-to-one, a coupon registered by the affiliated company. Thus, the present invention can diversify coupon information provision methods, thereby increasing an advertising effect, improving convenience of a user, and reducing maintenance costs.
