Wal-Mart is actively looking at the possibility of using drones to make deliveries to US customers, a spokesman said Monday, following the lead of Amazon and other retailers.
The retail behemoth has been testing the technology indoors "for several months" and on Monday made a request to US aviation authorities to do likewise outside.
In addition to deliveries, Wal-Mart wants to use the unmanned aircraft to keep a bird's eye view on its warehouses or other facilities, or to convey purchases in-store to customers' cars.
"This is part of our continuous efforts to drive efficiencies in our supply chain and to serve customers faster and better," a spokesman told AFP.
In March, the Federal Aviation Administration said it would allow online giant Amazon to carry out testing for its drone program.
The company hopes to develop a delivery system which would dispatch small packages in under 30 minutes.
