Actually, putting your card on your phone is a better protection against theft : they cannot be used without biometric identification, can be remotely revoked and you can still keep your plastic cards as backup.

I could easily live without it and I wouldn’t even consider it to be an important gesture for my next phone but it’s pretty useful when you have it.

Also, idk for Android but on iPhone it’s faster than plastic cards and more secure.

But I hope plastic cards are there to stay because that’s yet another thing locking us into the iOS/Android duopoly.
