Phones can be finicky…
If you have iOS 13.
iPhones that support reading and writing NDEF-formatted tags with apps like NFC Tools:
iPhone XS/XS Max
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.

The xLED is designed to show how location, rotation, and orientation of our x-series transponders affects how well they will couple to the magnetic field generated by a reader.
The xLED is made with thin-walled industrial grade glass, non-biocompatible epoxy resin, and would probably not even stand up to autoclave sterilization – DO NOT IMPLANT THIS PRODUCT. Besides, you wouldn’t be able to see the LED while holding a reader to it anyway.
