    Oh, I did a dumb. Capacitive readers use the body’s natural electrical signal to form an image of your fingerprint. You can trick them by using something conductive and running the right amount of electricity through.

    Dead people don’t work though. Not for very long at least.

      Capacitive sensors don’t measure the body’s signals. Capacitance is a physical property of a material. The sensor puts out a signal and measures the response.
