1. A wearable device comprising:
a charge interface comprising a first charge pad and a second charge pad; and
circuitry coupled to the first charge pad and the second charge pad, wherein the circuitry is configured to:
perform a charging process where the wearable device receives an electrical charge from a device to charge a battery via the first charge pad and the second charge pad;
cause a transition signal to be sent via the first charge pad or the second charge pad to the device; and
transmit data via the first charge pad or the second charge pad to the device.
