Smart Anti-Theft Bag

Smart Bag 1

The Smart Anti-Theft Bag is a compact, IoT-powered backpack that improves personal security using RFID authentication and real-time Telegram alerts. Built using an ESP8266 microcontroller, the system ensures that only authorized users can access the bag's contents.

When the bag’s zipper is opened, a 5-second timer starts. If no valid RFID card is scanned during this time, a buzzer sounds and a Telegram alert is sent. If the RFID scan is valid, the alarm remains off and access is granted.

This project uses an MFRC522 RFID reader, a piezo buzzer, a physical switch for zipper detection, and Wi-Fi-enabled cloud messaging via Telegram's Bot API. The logic was programmed using the Arduino IDE with ESP8266 libraries.

Key design considerations included timing precision, network reliability, and power optimization. The hardware is compact enough to fit inside any standard backpack.

This project demonstrates expertise in embedded development, IoT integration, and secure user access systems. It can be expanded with GPS tracking, fingerprint access, or a mobile app in the future.
