Abstract: A mobile device configured for currency exchange enables a user to cause funds in a first pre-established account and denominated in a first currency to be sent to a first transaction machine to purchase funds denominated in a second currency. The mobile device electronically receives second account information after a second account is created, with the second account being created responsive to completion of the first transaction. The created second account includes the purchased funds denominated in the second currency. Accordingly, the user is enabled, subsequent to the first transaction, to select a second account module in the mobile device that has since been configured with the received second account information of the created second account. The user can thereafter cause the mobile device to send that second account information to a second, different transaction machine to perform at least a second transaction in the second currency. Other aspects are disclosed.
