Dear Filip, you have a decisive advantage with Samsung Pay on your watch, because you don't need a watch nearby. You can pay with the watch in such a short time that you could never do with your mobile phone. It's also very secure, because you have to wear the watch to use Pay. If it is taken off your wrist, it will be locked. I can only recommend that you spend a few francs more for S.sung pay.

Simply download the Google Wallet app and define it as the default. Works perfectly.

I have both in my watch. You can set one as default. Each one of them can give you offers
