If you are using GooglePay or Samsung Pay, then your phone has NFC. If you are not sure, the fastest and easiest method to find out if you phone has NFC is to open Settings. Search for "nfc" in the field at the top. If Android returns a search result like NFC or Near Field Communication, then NFC is available on your Android smartphone or tablet.
Once you find the NFC option on your smartphone, you just need to tap on it to activate it. The switch next to it reflects that the feature is now enabled.
