Abstract

An online coupon distribution method includes creating, at a coupon distribution server and for a sold goods coupon, a pair of a code number and an authentication key which are stored in a coupon database. The code number is sent to a wireless communication terminal and the authentication key is sent to the wireless communication terminal using a callback short message service (SMS). When the sold goods store coupon is used at a goods store terminal, the code number is sent from the goods store terminal to the coupon distribution server. The coupon distribution server receives the authentication key sent from the wireless communication terminal through a callback SMS, and compares the received code number and authentication key with the code number and authentication key stored in the coupon database. The coupon distribution server sends an authentication result to the goods store terminal where the goods store coupon is used.
