If you have iOS 13.
iPhones that support reading and writing NDEF-formatted tags with apps like NFC Tools:
iPhone 7/7+
iPhone 8/8+
iPhone X
iPhone XS/XS Max
iPhone XR
iPhone 11
iPhone 11 Pro/Pro Max
iPhone models that additionally support background tag reading* are bold in the list.
*By background tag reading I mean:
- Reading NDEF-encoded links (NO vcards). No camera should be opened, screen must be on (you can read tags even before unlocking, just turn on the screen)
- Configuring ANY ISO14443 tag as Shortcuts app trigger (e.g. turn on wifi, play music when tag is detected)
iPhone 6/6+, 6s/6s+, SE and Apple Watch also have NFC but only for Apple Pay.
