Where is the NFC sensor on A21s?

[Makaveli999x]

On my old iPhone and huawei the sensor was at the top on the back above the camera

Is the NFC sensor on my new a21s further down?  Asking as  I tried paying how I used to in store but i had to hold the middle part to the terminal instead

doesnt matter where NFC is, just turn it on when u paying

it will work fews centimetres away from the contactless machine, so it doesn't matters where it was, but usually it in the middle of your device

Are you sure it's an A21s you have? Mine doesn't have NFC at all.
