Can iphones read nfc tags. Nonetheless this was a big step forward. Technically this correct encoding follows a universally recognised data structure called NDEF which stands for NFC Data Exchange Format. Get Decode NFC Reader.

I can read and write to NTAG 215 tags using NXP tag reader but when I write anything including a URL to the tag the iPhone wont pop up with a message to go to the link.

You can buy NFC tags in forms like wristband sticker tags cards and even rings.

If you thought the NFC tags come only in the shape of credit cards there are many interesting forms you could get the same as well.
Get a Dedicated NFC Reader App. Phones before iPhone 7 do not have NFC capability beyond Apple Pay. Unfortunately Apple did not open up NFC tag reading for the older iPhone 6 6 6s or 6s models.
