The quickest way to check your phone's compatibility is to open up the Golf TAGS tab in the preferences menu and see if any warnings are displayed.
Golf TAGS use technology called Near Field Communication (NFC). Most Android phones and iPhones have it nowadays. You can check the full list of NFC-enabled Android phones here. iPhones 7 or later with iOS 12 or later are supported. iPhone SE is not compatible with tags. Android phones must run Android 4.0 or later.
Older Golf Pad TAGS may not work with iPhone, see this article for more information.
If you aren't sure whether your phone is compatible, please send a quick email to firstname.lastname@example.org and we will confirm it for you.
