Apple's Pay started well and has grown at a steady clip. But at Apple's Watch event, Tim Cook has announced just how much it's taken off in the last month or so: It's now accepted at over 700,000 locations. That now includes Coca-Cola machines, up to 100,000 of which will take the wireless payments by the end of the year. For some perspective, we reported about a month and a half ago that Apple Pay was accepted at 200,000 points of purchase, meaning recent adoption has accelerated at a breakneck pace -- and it'll soon get a boost from Apple Watch users. The only drawback? That success has attracted throngs of fraudsters, forcing banks to adapt quickly by tightening security.
