About this app

TapSense shows you exactly where your phone's NFC antenna is, so you never fumble again when tapping to pay, unlocking a smart lock, boarding transit, or badging into the office.

Can't find the NFC chip location on your phone? Wondering where the NFC antenna is on your Samsung, Pixel, OnePlus, or Xiaomi device? TapSense finds it for you - no guessing, no digging through support forums.
