1. A user-worn device comprising:
an ultrasonic transducer configured for contacting a first body-part of a user wearing the user-worn device, and transmitting data between the user-worn device and a touch-device encoded in ultrasound via a second body-part of the user contacting the touch-device, and
a processor being operative to:
receive, from the touch-device, in response to the second body-part of the user contacting the touch device, an indication identifying data which is required by the touch-device if the user shall gain access to a specific application operation or service operation which is accessible to the user-worn-device when selected by the user with the second body-part touching the touch-device;
obtain the data required by the touch-device, according to the received indication, in response to receiving the indication;
control, in response to obtaining the data required by the touch device, the ultrasonic transducer contacting the first body-part of the user and the second body-part of the user maintaining in contact with the touch screen, to use the user's body as the data transmission medium to transmit the obtained data to the touch-device by employing the ultrasonic transducer to produce ultrasound, wherein the produced ultrasound is operable to travel from the ultrasonic transducer to the touch device via the first body-part and the second body-part, and wherein the obtained data is encoded in the produced ultrasound; and
gain processor operational access to the selected application operation or service operation, in response to the obtained data being transmitted with encoding from the ultrasonic transducer to the touch device.
