Integrating with a Payment Handler

Abstract

Anyone who knows me personally will know that I’m often in my local corner store – I’ve become something of a regular, having been visiting it regularly for over a decade. Over time, I’ve seen people walk up to the checkout, whip out their mobiles or even certain smart watches, and wave them past the credit card machine. Yep, the days of paying by card are numbered, or as some might say, fast becoming old-school!
