Abstract
Data terminal equipment 3.sub.1 receives a bonus-attached file including a shop bonus provided to a user, and a bonus identifier for uniquely identifying the bonus, and stores the bonus identifier included in the bonus-attached file. Data terminal equipment 2.sub.1 previously stores another bonus identifier for uniquely identifying the bonus provided to the user of the data terminal equipment 3.sub.1. Through data communications with the data terminal equipment 3.sub.1, the data terminal equipment 2.sub.1 requests the bonus identifier on the data terminal equipment 3.sub.1 side. If determining that the bonus identifier received from the data terminal equipment 3.sub.1 is as being the same as the data identifier stored therein, the data terminal equipment 2.sub.1 provides the bonus specified by the bonus identifier to the user of the data terminal equipment 3.sub.1. In such a manner, the data transmission system is improved in user's usability with no more need for printing coupons.
