PURPOSE: The most appropriate card recommendation, in situation of card payment, recommends the most appropriate cards when a client selects a category, by classifying each vendor and each product into categories. CONSTITUTION: Information, which each card company offers, is collected, and the collected information is stored in database. If a client selects a category he hopes to use, the client is identified if the client is a member. If the client is not a member, the most appropriate card, which is the closest card with discounts of the selected category, is recommended in order. If the client is a member, the client is identified if the client has a main card and some cards. |
