We created this platform based on SAAS model, We used MEAN stack, socket.io, amazon AWS, and native technologies for mobile apps, we developed real time API protocol as a layer so any action that needs to be done in real time can be achieved with out any other method like pooling. Now as soon as golfer check in to any golf course he get alerted if there is cart available or get error if no cart available, in case of availability as soon as a golfer submit an order, the most nearest cart user receive his order with accurate hole number with out any delay. He delivers the order and golfer completes his payment.
