Abstract

A remote device configured to wirelessly communicate with a computing device without using RF signaling. Embodiments of the remote device may include a processor; a memory coupled to the processor and configured to store data; one or more transistor(s); and one or more output pad(s) operatively coupled with the one or more transistor(s). The processor is configured to cause the one or more transistor(s) to selectively ground one or more of the output pad(s). The one or more output pad(s) are configured to be selectively grounded to impose a capacitive load pattern on the capacitive sensor of a computing device, the capacitive load pattern encoding the data. The pattern is detectable and decodable by the computing device to recover the data. Embodiments of the remote device may include a photodetector to detect light pulses from the display of a computing device, the light pulses representing data from the computing device.
