how to add Links to already existing NFC tags/ OpenPath ID Card

Make sure you have a nfc capable phone. This will include any iPhone above the X and any android past galaxy s8.

Go ahead and download the " NFC Tools" app on the iPhone which will let you write onto an nfc tag. 

Next you'll want to select the write option in your NFC app which will write onto that tag. Remember we do not want to erase what is on the tag. Thankfully on the iPhone you are unable to erase items from an NFC.

Once selected add the proper link you want to add to that card, lets say something like linktree.com. Once added be sure to hold the ID card near the phone and you should feel a buzz and a screen pop up saying done. 

Then you can test this by tapping your phone onto the card which in turn will give you a notification to open the link that you added.
