Where is the sensing area of HTC609d Telecom Edition using wing cartoon?

Smart cards on mobile phones, if the SIM card has a small tail, the sensing area is at the end of the tail. If there is no tail, it is integrated on the SIM card.

It should be noted that the back cover of a mobile phone is preferably non-metallic, and the front and back sides of the induction coil are written on the coil.

I use a mobile card. The SIM card is connected to the card with wires and stuck around the battery. Just brush the back cover of the phone when you brush it. Or you can take the card off and try it, or you can swipe it. If it doesn't work, go to the business hall and change it.
