A dozen transits systems in the U.S. and overseas also currently support Apple Pay or will soon, the company said.

For its part, CVS says about 7,800 stand-alone pharmacies will accept Apple Pay, quite a turnaround from Oct 2014, when the drugstore chain stopped accepting Apple Pay payments, over a conflict at the time with another mobile payments system called CurrentC, that eventually failed before it ever really got going.
