If you're going to argue that one thing is easier than another, then yes, counting movements and time is part of that.
"That'll be $15.77"
Option 1: I look in my wallet and find a ten and a five, put my hand in my pocket and grab a few coins, hand those over. The cashier takes the cash, taps a number into the till, finds the right change and hands it back. Is it arduous, hard labour and the end of the world? No of course not, but it is what it is.
Option 2: I look at my phone to unlock it and wave it over the thingy. Job done. I don't even have to remember to withdraw cash from the bank before I go.
It's easier and quicker, for you and for the cashier. The shop knows it too, particularly supermarkets - they encourage people to use faster payment methods so they can shave even a few seconds off a transaction and push more transactions through at peak times.
It's kinda funny, it used to be that "can I pay by card?" caused cashiers here to sigh and get a little annoyed by having to process a card payment. Some scolded me that I should've told them sooner (though exactly when was never clear to me). Presumably their POS systems were geared towards cash payments and card payments were bolted on as an afterthought.
You forgot to mention you no longer need to check your change at the end. You have a record of the transaction on your app and you were able to verify the amount before swiping.
