Walmart offers a new payment app for its stores. This is another signal of the rising trend of digital payment, as well as a deliberate choice of an independent payment option (rather than Apple Pay and the likes). Another retail giant, Costco, allows credit card payment through Visa alone. These examples demonstrate how your customers (or, those choosing not to be your customers) can influence your industry – take this into consideration.
