Project description:
"I already have a fingerprint scanner collecting daily attendance; what I am missing is a seamless bridge between the device and my web application. I need every new scan—employee ID plus exact check-in time—to appear in real-time (or as close as possible) inside my existing attendance page. The integration must also work both ways: whenever I change an employee’s end-date or validity inside the web app, that update has to be pushed back to the device so the data stays consistent on both sides.

Here is what will make the job a success for me:

• A reliable service (API, background job, or webhook—whichever fits best) that continuously pulls fresh logs from the fingerprint scanner and inserts them into my database without duplicates.
• A reverse-sync routine that listens for end-date edits in the web app and updates the same record on the scanner.
• Clear, commented code plus a short README explaining configuration, dependencies, and how to add new devices later.
• A quick hand-off session once everything is live so I understand the flow and can maintain it.

Please highlight your direct experience integrating fingerprint attendance devices—SDKs you used, brands you connected, or similar projects shipped—when you respond." (client-provided description)
