Re: This is all because the West is far behind
Right now if a card doesn't work you get a replacement for free. Good luck when everything is inside your phone, requires it to be powered and working, and may require you to buy a new phone just because they upped the required spec (just got a message about that from my bank...)
Moreover if you're abroad it the phone requires an internet connection for the app to work it may become quite expensive if your contract doesn't cover rovers fees abroad, worldwide.
It's the "all eggs in one basket" security risk
