Grabango has launched a pilot study at supermarket chain Giant Eagle Inc. that allows shoppers to purchase goods using its checkout-free technology that bypasses traditional cashier lines. 

The companies are testing a service that offers two options to shoppers, either a mobile-app based solution and the second system that allows consumers to pay with any tender they want. The systems use computer vision and machine learning to automatically track goods as customers browse store shelves. 

"Giant Eagle is committed to advancing technologies that create an improved, stress-free shopping experience for our customers while still protecting their privacy," Dan Donovan, spokesman for Giant Eagle, said in the announcement. 

Giant Eagle has annual sales of $8.9 billion and more than 460 stores in Western Pennsylvania, Ohio, West Virginia, Maryland and Indiana.
