A personal and peripheral data communication device is provided to communicate data in a real-time fashion with a host. The device distinguishes two different modes. The first mode is an active data mode to enter data or retrieve previously entered data. The second mode is a responsive data mode to enter data or retrieve previously entered data. The responsive data mode is triggered on the device by the host or by an application running on the host. Data can be stored on the device and securely protected against unauthorized access by biometric and/or non-biometric means. Data can also be authenticated or secured by cryptography via biometric and/or non-biometric means prior to transmission to the host. The device can be used with a variety of different hosts, and is irrespective of the operating system running on the host or type of application with which the device desires to communicate.
