Amazon Go is a convenience store concept that allows customers to walk in, take what they want, and walk out without waiting in line or making a purchase. Using palm scanners and computer vision, the stores keep track of what items customers take and charges their Amazon account. Since opening its first store in 2018, Amazon Go has expanded to 27 stores across the US and UK. The secret to its success is an attention-catching, easy to use shopping experience and partnerships that could allow its just walk out technology to be adopted by other retailers.
