Smartphone OCR and database app

The company has several roaming purchasing agents who buy specific electronic items from individuals that sell them privately. I require a smartphone app that will let each agent manage his purchased inventory. The aim is to let agents add the purchased item to the online database, instantly. REQUIREMENTS The app will allow agents to add the following three values (from new inventory items) to an online database. 1) Make 2) Model 3) Serial Number Each agent must login to manage his inventory. All items are readable by club members who may want to buy an item. Club members can search by Make, Model and Serial Number. The app should give an agent the choice to use the smartphone in OCR mode or Manual mode. In OCR mode the app collects data using the camera. The software should try to auto-populate one or more fields automatically. For example, by searching for string "Model" and/or "Serial" and then reading the information that follows the string. In Manual mode, the user can submit the data manually via a form. In both modes, OCR and Manual, the user should be able to make changes and confirm the values, before submitting the data to the online server. NOTE * This document describes the basic functionality only. Detailed software specifications will be provided, later. ** Over time, the app will be expanded with more functionality and features. *** The current number of fields (three) may change.
