A method of using a multi-function card comprising the steps of: a) a user establishing a reward point account directly with each of a plurality of reward points issuing entities, wherein each of said reward point accounts is stored on a multi-function card, and wherein each of said reward point accounts tracks points earned by the user for transactions between the user and the associated reward points issuing entity, and wherein each of the reward points issuing entities enables the user to selectively redeem points from the reward point account associated with the user for an item selected by the user, b) the user earning reward points from each of the plurality of reward points issuing entities, each of said reward points issuing entities storing the user's earned reward points in the user's reward point account stored on the multi-function card, c) the user establishing a reward exchange account on the multi-function card, d) the user designating at least some of said earned reward points from one or more of said user's reward point accounts for trading into the reward exchange account, e) the multi-function card accumulating the user's designated earned reward points from each of said designated reward point accounts into the reward exchange account associated with the user, and f) the user using the multi-function card to redeem accumulated points from the user's reward exchange account on the multi-function card for an item selected by the user; whereby portions of available reward points may be selected from selected reward point accounts for accumulation into the user's reward exchange account on the multi-function card, and optionally leave other portions of available reward points remaining in said selected reward points accounts for subsequent redemption with the associated reward points issuing entity or for subsequent accumulation into the user's reward exchange account.
