How to Set Up a Barcode Tracking System for Library Attendance?
Asked by

Hi everyone! I'm looking to switch our library from a traditional logbook system to something more tech-friendly. I want to create a system that tracks student attendance using barcode scans from their ID cards. I have some familiarity with MySQL and Visual Studio Code, but I'm uncertain about how to start this project. What do I need to consider or learn to make this happen? Any tips, resources, or guidance you can offer would be greatly appreciated! Just to clarify, this system will track when students enter and leave the library, not the book borrowing process since we already have a separate management system for that.

Great idea! When you scan a barcode with a scanner, it typically acts like a keyboard input. You’ll need to build a database to store user and attendance data. Think about the tables you’ll need; maybe a User table, an Attendance table, and a way to log the timestamps. It could get complex, especially if you're new to full application development, but it's definitely doable if you plan it out right!

Definitely check GitHub for open-source projects related to attendance systems. There are many community-proven solutions you can adapt. I can recommend some examples: look at RFID or ESP32-based attendance systems. These usually come with a dashboard and can track entry/exit effectively. Just adapt them to use barcode scanners instead!

You have a couple of options here. One approach is to use a Raspberry Pi with a USB barcode scanner—plenty of guides online for that. Alternatively, you could go for a camera-based system, but it might be trickier without much experience. Here’s a project you might find helpful: look up how to interface USB barcode scanners with Raspberry Pi.
