Banks generally don't like disposable digital purse cards. They make money off fees and interest. If a product doesn't rope you into a customer "relationship" where you link your pay deposits or later might get a mortgage or car loan they can only make money off fees. Enjoy paying $5 to activate a $100 prepaid debit card!
Using Google or Apple Pay so I can tap my phone instead of my card gives me no extra benefit that I care about and complicates my ecosystem with another party.
Only in the U.S. In many other countries the processing fees are regulated by the government so the banks can't afford to give you your "cash back".
