An electronic asset exchange system includes a communications medium and at least two electronic purses. Each electronic purse includes an interface configured to send and receive messages, a memory storing a current asset value amount, a respective unique identifier, and a log of asset transfers; and a controller. The controller receives an asset transfer message including at least an asset value amount to be transferred, and executes a Transfer-in process to increase the current asset value amount by the asset value amount to be transferred and record information of the asset transfer in the log. The controller receives, via the interface, an asset transfer request message including at least an asset value amount to be transferred, and executes a Transfer-out process to generate and send an asset transfer message including the asset value amount to be transferred, decreasing the current asset value amount by the asset value amount to be transferred; and recording information of the asset transfer in the log. |
