for businesses who don’t have the skills it could be useful, when they want stuff like new address for every payment, maybe some administration etc, it is not needed: they could just use one address, or at least one address per customer or something, depends on the size of the company how much effort it is going to cost them (bakeries, icecream carts, vs wall-mart etc) , im sure at least until they have learned how to do it themselves there will be demand for something like this, lets call it NuPay
