Walk-Out-To-Pay For The Average Merchant PYMNTS.com

There could be so much more to a cashier-less checkout experience -- and for so much less than what Amazon is spending to do it at its bespoke Amazon Go convenience and grocery stores. That's not to say Amazon Go is a bad system; it just won't work for every merchant. As Amazon Go has demonstrated, walking out the door to pay may be the ultimate in terms of a seamless checkout experience. Customers at the eCommerce giant's brick-and-mortar mini-mart simply go around the store adding the items they need to their shopping cart, then leave the store -- triggering an invisible payment to initiate using their Amazon account. One of the main problems with Amazon's technology, however, is that creating the experience requires heavy investments in hardware that not every retailer can afford to make.
