A nontraditional transaction device, for example a mobile device, may be employed to complete a transaction. The mobile device may utilize radio frequency (RF) communication and/or authentication to facilitate completion of a transaction. Secondary identification information, for example voice recognition data, biometric recognition data, or alphanumeric data, may be utilized for secondary end user authentication. For security reasons, the mobile device account data may transmitted after the secondary identification information is verified. |
