We embed a pass in the phone
Today, a very large number of people use contactless passes: at enterprises, in a dormitory, etc. This pass is also called a “tag”. Some of the most common RFID passes are with an operating frequency of 125 kHz. According to the internal structure they consist of a wire coil and a microchip.This pass is certainly not large, but still it’s not so convenient to carry it every day. Yes, and if you forget, then returning home for a pass is not very pleasant.I will show you a way to embed a pass card in a cell phone. So, take a pass and soak it in acetone for 1 hour. The main thing is not to overdo it, so that acetone only eats plastic, and not a coil with a chip. Take care of ventilation, as acetone is very toxic. Keep the pass in acetone, in a container that closes to prevent excess vapors from evaporating. And be sure to ventilate the room. After an hour, gently blueness the plastic.And Gently exfoliate the separated layers. Get the reel with the chip.
