<h3>Overview of the project</h3>
<div>
<p>To have a general idea about the project you can view <a href="/files/presentation.pdf">the slides of the
presentation</a>.</p>
<p>The system is a prototype of a self-checkout cash register for a generic supermarket. The system enables users to identify themselves and scan the products they bought.</p>
<h4>Client side (board)</h4>
<p>The client side is made with the <a href="https://www.ghielectronics.com/catalog/product/432">FEZ Spider
II</a> connected to some peripherals. It is the device that allows user to interact with the system, scanning the codes and using the GUI on the touchscreen.</p>
<p>For taking better pictures we made a "black box" around the camera, that internally contains some LED lights and has a small window on the top that can be used to expose the barcodes / QRcodes.
</p>
<p>The role of the client side is to send images to the server, display information on the screen and interact with the buyer, allowing the creation of receipts.</p>
<p>See <a href="/files/inside.jpg">what's inside the black box</a>.</p>
<h4>Server side</h4>
<p>The server receives images from the client and performs a lookup in the database, returning informations about the user and about the products.</p>
<p>It has a basic GUI for logging and to see the pictures sent from the client.</p>
<h4>Database</h4>
<p>The database is responsible for keeping persistence of the data: it contains the data about the products, the users, the receipts and has some other tables that allow reordering products from the warehouse when the shelves are nearly empty</p>
<h4>Website</h4>
<p>The website is a useful tool to let the user see their purchase history and the collected points, and allow the administrator to see purchases and to manage the inventory.</p>
