We embed the pass into the phone
Today, a very large number of people use contactless passes: at enterprises, in hostels, etc.
Such a pass is also called a “tag”. Some of the most common RFID badges have an operating frequency of 125 kHz. The internal structure consists of a wire coil and a microchip.
Such a pass is of course not large in size, but it is still not so convenient to carry it with you every day. Moreover, if you forget, it’s not very pleasant to return home to get your pass.
I'll show you a way to embed a pass card into a cell phone.
So, take the pass and soak it in acetone for 1 hour. The main thing is not to overdo it so that the acetone only corrodes the plastic and not the coil with the chip. Take care of ventilation, as acetone is very toxic. Keep the pass in acetone in a container that is closed so that excess vapor does not evaporate. And be sure to ventilate the room.
After an hour, carefully blue the plastic. And Gently separate the separated layers. Take out the reel with the chip.
The little black dot on the microboard is a chip with information.
Next, take a cell phone. Remove the back cover.
Place the reel with the chip on the back wall. Apply nail polish. Waiting for it to dry. Several layers can be applied.
All. Close the phone cover and check.
In principle, there is nothing complicated here. The main thing is not to overdo it with soaking in acetone and not to break the wire when transporting from one place to another.
Now you don't need to carry your pass with you, and your phone will always be with you.
