Convenience?

Set up once with the CC with rewards for groceries, hover hand 2 seconds, done.

Apple Pay in the phone or watch are super convenient as well, but they take just a tad bit more of time between selecting the menus in the touch screen for pay options, and then selecting the matching CC.

I save like 30s? Possibly. Is this tech overkill? Most likely.
