I tried it with an NFC compatible device but it doesn't work

If after following all the steps in the article My Tapni tag is not working, there is still nothing when you hold the product on the NFC reader, follow the below steps:

Step 1: Download the NFC Tools app available on Apple Store and Play Store

Step 2: Click on "Read"

Step 3: Tap your Tapni card with your phone

Step 4: Send us a screenshot of all details and a photo of your QR code here.  

Please note that we need the FULL screenshot with all the details (from top to bottom), so that we can help you out immediately.

In case the app NFC tools does not detect the Tapni, please send us a video proof of the  scanning.
