The enhanced TNG card must be scanned directly at the back of your mobile device for the Near Field Communication (NFC) to work.
For iPhones, scan the card at the top part of the phone’s back beside the camera, whereas for Android and other brands, scan at the middle of the phone’s back. This process may require some trial and error depending on your device.
For best user experience, please check with your device manufacturer on the NFC reader’s placement on your device prior to using the enhanced TNG card with your device. Please ensure that you’re scanning the card on the back of your device for longer than 5 seconds.
