Cash for most things, and just use a card like normal otherwise.

I don't really see the appeal of contactless payment, pulling a card out really doesn't take much time.

Cards are "contactless payment" these days.

Google Pay (Google Wallet) actually also has virtual number so my real card number won't leak in many cases.

Just having to take your phone with you is quite comfortable. Your phone is probably the pocket-sized item you are unlikeliest to lose.

True, but I also need my license to ride my motorcycle or drive a car, plus cash needs to go somewhere.

+ my country already has a mobile driver's license app

And most places take card (or nfc via google/apple pay)
