This is a special shopping cart.We divided the original shopping cart into two parts--the shopping basket and the cart body . With a unique retractable mechanism connected and the vehicle body and the shopping basket can be easily split and combined. So that each part can be used independently.When you waiting in line, just remove the cart body ,and put it on the conveyor belt next to the cash register,it would relieve your stress when you paying.
