The first Lenovo Lecoo Unmanned Store is located in Beijing, at the company's tech campus. Its goal is to help Lenovo test its facial recognition, electronic payment, IoT, AI, and AR technologies. The catch is that Lenovo tablets are being used instead of the human staff one would expect to see in a store.
