The zero-cost virtual "electronic fence" technology realizes that the bicycle can only be returned inside the fence, and can not be returned outside the fence. While facilitating the use of tourists, it ensures orderliness of the tourist area.

The charge, deposit and rent of bicycles are implemented by tourists themselves, which is convenient for tourists and reduces the cost of manpower maintenance.

"Zero-cost" site can be built on demand, as many parking places as possible greatly reduce the difficulty of borrowing and returning bicycles. At the same time, tourists have more points of contact with bicycles, which can greatly improve the willingness of tourists to rent cars and increase their rental income.

Tourists can borrow bicycles and pay fees by themselves to avoid the possible loss of funds caused by manual services, and the funds can be monitored in real time.
