The invention allows the imprinting or stimulating of acupuncture meridians for 5 to 10 minutes through touching, with an index finger for 30 seconds to 2 minutes, a displayed image on a smartphone of reflected scattered light modulated by coherent domains in cardboard card which are modulated by a magnetic field at the acupuncture endogenous frequencies. The image of the reflected scattered light modulated by acupuncture endogenous frequencies can be photographed by a smartphone digital camera on a white cardboard card against a low frequency voice coil with the endogenous frequencies energizing the coil.
