In selected embodiments, a computer system implements a virtual currency that can be purchased using a variety of ways, including cash and foreign exchange; wire and similar transfers; trade in of various rewards, airline miles, and unused gift cards; as well as in other ways. Vendors can provide effective discounts and incentives through real time setting of exchange rates between the virtual currency and an existing currency such as legal tender (e.g., dollars), for using the virtual currencies in their stores. The incentive, the fee of the operator of the system, and additional available discounts/coupons may be provided at the point-of-sale. |
