A methodology and
system allows a plurality of reward scheme owners to give differential rewards, through a plurality of reward distribution agents, to various users based on the
user profile. The reward scheme owner may be a seller, a manufacturer, a
sales promotion agent or even an intermediary. Similarly, the reward distribution agent may be an on-line or a physical retailer, a broker, a seller or an intermediary. Also the users may be consumers, businesses, brokers or other intermediaries. In one specific case, a reward scheme owner defines a plurality of reward schemes, including at least one differential reward scheme giving different rewards to different users. The reward scheme owner communicates these to a central reward scheme
database server. The reward scheme owners may or may not advertise these schemes. The user visits an online or a physical store. The store acting as a reward distribution agent dynamically profiles the user, queries the central reward scheme
database server if the
user profile meets the criterion for one or more rewards and offers the applicable rewards to the user. The store later receives reimbursement for the rewards offered to various users, from the reward scheme owners. This methodology and
system may be used for offering targeted or differential discounts on different products and services, offering different promotional schemes on different combination of products, giving loyalty points, electronically distributing prizes, free samples, product warranties, tie-in promotions, cross selling, up selling, premiums, memberships, card discounts, organizing contests, sweepstakes, games and offering other similar rewards.
