# Test Interface

The **Test Interface** in the CloudBox allows you to quickly verify that your RFID reader and its connected antennas are working correctly. This is especially useful during setup or troubleshooting, ensuring that each antenna is detecting tags as expected before starting a live timing session.

The interface represents each available antenna (1–8) as a circle on the screen. When a tag is detected, the circle becomes active and displays key information such as the tag’s code or EPC, the time since it was last seen, and the signal strength (RSSI, if available).

Operators can start or stop the test directly from this interface, making it a convenient tool to validate system readiness.
