“What if the fingerprint device stops working?”

You switch to manual mode instantly. We ship a replacement the same day. And every record auto-syncs once it's plugged in.

Built for Real-World Conditions

Plug-and-Play Hardware

DRAIS supports major biometric scanners out of the box. We configure, test, and install the devices at your school — staff just supervise.

USB & Network Modes

Devices connect via USB for local setups or TCP/IP for networked campuses. Both modes support offline caching automatically.

Auto-Sync on Reconnection

If a device goes offline, all cached attendance data syncs automatically the moment connectivity is restored. Zero manual intervention.

Instant Failure Alerts

If a device stops responding, our monitoring triggers an alert. Your school and our team are notified simultaneously.

Same-Day Replacement

We maintain spare device inventory for every region. If a scanner fails, we dispatch a replacement the same day.

Manual Override Mode

While a device is being replaced, staff can record attendance via the DRAIS web interface. Records merge seamlessly once hardware returns.
