The location of a phone's NFC antenna changes between phone brands, and between models.
A phone's NFC antenna is located on the back of the phone, but it can be anywhere: top, middle, or bottom. Finding your phone's antenna, or NFC “sweet spot” as we like to call it, can be a case of trial and error as the location of the antenna is not usually indicated.
iPhone 7 and onwards are NFC enabled. Apple makes things easy for NFC users, as iPhones come with NFC permanently switched on.
Android Phones have supported NFC for much longer than iPhones. It is estimated that 90% of Android phones in the market have NFC capability today.
Some Android devices come with NFC turned OFF by default. If you’re rocking an android and can’t get NFC to work, have a look in your settings to see if NFC functionality is turned on.
This blog will help you to find the location of your NFC Antenna, or ‘Sweet Spot’ as we like to call it.
