For iPhones: Place your Tapni Sticker on the bottom of your phone. If you place it at the top, it will set off your phone's reader constantly.
For most Androids: Place your Tapni Sticker on the bottom as well.
For Galaxies/Notes: Place your Tapni Sticker at the top of your phone next to your camera.
Before sticking your Tapni please make sure to put it at the right place. If for any reason you decide to take it out, we do not guarantee that the glue will be fully resistant.
Make sure and try a placement that doesn't trigger your phone's NFC reader before you place your Sticker.
