Each chiplet will itself have up to 100,000 transistors and include a two-way radio, data encryption engine and way to detect tampering—all while consuming under 50 microwatts (50 millionths of a watt) and costing less than one penny each. Identifying information on each dielet would be read using a penlike probe plugged into a smartphone.. a dielet would be inductively powered by the probe, which would communicate via radio frequency signals when placed within a half millimeter of the chiplet. The probe would relay encrypted information to an app on the smartphone.
