As shown in the images, when the circular logo is brought close to the phone's NFC (in the enabled state), the yellow LED lights up, and the rocket on the front will show a flame at the bottom. The silkscreen displays
a map and lyrics.
The switch toggles which NFC chip is used.
A JLCPCB four-layer PCB is used, concealing the NFC coil wiring. While visible to the light, the surface is not visible and does not interfere with the silkscreen display of the circular logo.
