Why add it? Manual attendance is slow and prone to fraud. Manual attendance could still be other options for those that cant afford the device at initial stage.

How it works:

Hardware: The school buys a ZKTeco or similar biometric device (Fingerprint/Face ID).

Sync: This script pulls data from the device and hits your SaaS API (POST /api/attendance/sync).

Result: Parents get an instant push notification: "John arrived at school at 7:45 AM."
