The goal of the Pestan application is to enable monitoring the usage of Zebra Handheld TC 8000 device in the work process of the company and at the same time, to allow Admin User to follow and control the process. Zebra Handheld TC 8000 is a new warehouse mobile computer designed to deliver productivity increase in the warehouse. Our client Peštan wanted the same result – less time to complete the job and the increased productivity. Zesium, as a technical partner, took a leading role in building a system that will help our client achieve the wanted result. The system for Peštan was done in three parts: Web Admin application is used to show the analytics of Handheld device usage, send notifications and creating the usage reports. Android Handheld application’s goal is the manage the authentication of the users as well as gathering data about the usage of the Handheld devices. Backend was also done by Zesium and it is written in Java using Spring framework.
