Japan ticket gates are open by default, closing only if someone hasn’t presented a valid ticket. Mobile IC express transit doesn’t require opening an app or unlocking the device.
Advantages compared to a closed/open gate system include energy saving, time saving, safety. You do need a honest user base.
