I really like it. it's comfortable.
the program it uses is called NFC, you can find it in your notification bar.
it is not used in all devices, mine doesn't have it so it won't work.
check if your phone has it before buying it.

Very fast delivery need to be tested

Too much top!! Perfectly fuels! The phone has to have the NFC function and it must download the near field communication NFC app!! Use on Samsung devices more can work on other devices!! recommend!!! Arrived well packed!! Good seller!! I recommend
