NFC tags with iOS13

in iOS 13 using NFC stickers is even easier and more fun it seems.

But: which type of stickers are the best fit for the iPhone and iOS13?

most all of them work.

There are special stickers that work on metal if you are going to stick them to something metal.

I’ve seen Nintendo Amibos work. I want somebody to tell me if they can get the NFC chip inside their cat or Dog to work.
