For example, the Mask 1.0, the map, that was Howard Wu’s idea. As for Mask 2.0, that was Chi‑mai’s idea and implemented by Trade-Van, which was the company that did the tax filing software idea. On the 3.0, that was tested by the Taipei Smart City with Yallvend, the startup that did a vending machine. Then the convenience store came to me and said, “Yeah, we can do that too.” [laughs]
