Prepare your URL or Message

If you are going to program your NFC product to open up a URL (like Facebook, Venmo, etc) then move onto the next step!  But if you are wanting to write a text message (like emergency contact info for your child, a love note or some other message) please use the Text Generator.  I created this Text Generator so that any Android or iPhone with NFC can easily tap and read a message.  There is currently NO OTHER way of saving a text message on any NFC for both Android and iPhone.

Your text content is never stored on our servers. The text you enter is encoded directly into the URL and only exists in that link. When someone scans your NFC tag, the text is displayed purely from the URL parameters - no data is saved, logged, or transmitted to any database.

💾 Memory Info

Depending on the product you purchased, some NFC tags have 180 bytes of memory while others have a little more.

Click on WRITE once again.  Gently place your NFC product near the top part of your phone so the app can add the URL to your NFC tag. If the NFC does not save, it may be that the URL is too long or the NFC was moved away too fast.  After it saves successfully, you will see a checkmark on the screen.  Close the app and try tapping the NFC with your phone once again. Make sure your phone is unlocked when you try to tap the NFC.
