But the main emphasis will be placed on testing the effectiveness of this technology and on trying to introduce the receiver into a smartphone. Inside there is an inductor and a receiver board.
Opening the receiver went smoothly. Along with the case-book, a base-transmitter and a universal receiver came in the form of a sticker on the smartphone case https://jiji.co.ke/jewellery-and-watches/gemstone.
