The quickest way to check your phone's compatibility is to open up the Golf TAGS tab in the settings menu and see if any warnings are displayed.
Golf TAGS use technology called Near Field Communication (NFC). Most Android phones have it nowadays. You can check the full list of NFC-enabled phones here. Your phone also needs to run Android 4.0 or higher. 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.
