Project description:
"I’m looking for a straightforward PHP-MySQL web app that lets each employee record when they come in and when they leave. The flow should be simple:

1. The employee scans a one-time QR code or taps an NFC tag (I’m flexible on whichever non-copyable method you recommend).
2. A web screen—built with clean PHP/HTML—immediately appears, asks for the employee’s ID + password, then shows two buttons: “Entrance” and “Exit.”
3. When the employee taps one of those buttons and then “Confirm,” the server writes an immutable timestamp (server time, not client-side) to the database.

Core requirements
• MySQL schema for employees and the in/out log.
• PHP scripts for authentication, scan detection, and the confirmation page.
• Protection against users editing the stored date/time or resubmitting the same event twice in a row.
• A minimal, mobile-friendly interface—no fancy styling needed, just functional HTML/CSS.
• Clear setup instructions so I can deploy on a standard LAMP stack.

Nice to have (but not required if it stretches scope): an admin screen to export logs to CSV and quickly add or deactivate employee accounts.

If you’ve built similar attendance or access-control tools, mention it and share a quick demo link or screenshot. Let me know your estimated timeframe and any questions you have about the flow." (client-provided description)
