-# SekiPOS
+# SekiPOS v1.0 🍫🥤
 
+A dry-humored, over-engineered POS (Piece Of Shit) inventory system for software engineers who scan too many snacks. Uses a hardware barcode scanner (via Serial) or a phone to manage products with real-time UI updates.
+
+## 🚀 Features
+- **Real-time Inventory:** Instant UI updates using WebSockets (Socket.IO).
+- **Auto-Discovery:** Fetches product names and images from Open Food Facts API.
+- **Image Caching:** Locally stores product images to prevent IP bans and broken links.
+- **Chilean Formatting:** Native CLP currency support ($1.234).
+- **Security:** Session-based authentication (Flask-Login) with hashed passwords.
+- **Hardware Bridge:** A dedicated script to bridge Serial (COM) scanners to the web server.
+
+## 🛠️ Tech Stack
+- **Backend:** Python 3.x, Flask, SQLite
+- **Frontend:** Vanilla JS, Socket.IO, HTML5/CSS3
+- **Communication:** HTTP REST + WebSockets
