This application’s aim is to provide real-time visibility of the equipment through transportation, sterilization, storage, and use. This helps healthcare providers replenish the stock of sterilizable tools with greater efficiency. The system provides real-time location tracking of the equipment and auto marking of shipments as in transit and delivered based on its location. It has four parts:

Salesrep: It is an iOS and Android application using which a sales representative of the company can track the status and location of orders/cases assigned to him, and can also place new orders. Users can also see details of their past and future orders as well.

Carrier: This app is used by carrier users responsible for delivering the equipment from the warehouse to hospitals. This app provides real-time locations of shipments, having iBeacons attached, and provide the functionality of manually delivering the shipment and taking shipment receiver’s signature.
