Abstract
Devices that receive data while not directly powered and methods of operating devices that receive data while not directly powered are described herein. One or more device embodiments include an interface configured to receive data from an additional device while the device is not directly powered, a memory coupled to the interface and configured to receive the data from the interface while the device is not directly powered and store the data while the device is not directly powered, and a user interface configured to permit a user to interact with the computing device. The computing device is configured to operate in at least two different power modes, wherein the computing device is powered only via the interface while operating in a first power mode and the computing device is powered by a non-radio frequency (non-RF) power source while operating in a second power mode.
