Green means the student is allowed to enter.
Yellow means the ID is not recognized. The student is most likely using an old ID. If you are not using MOOV ID cards, and the card was just produced, there is likely a syncing issue with the ID moving from your badging software into MOOV.
Red means the student is not allowed to enter/exit the room. The student may be trying to enter the cafeteria when they have class, exit class when the bathroom is full, etc. The teacher will see a red notification appear on their screen with a reason.
Connection states:
Purple means the reader is attempting to send the tap to the SIS.
Yellow flashing means the reader is attempting to connect to your WiFi.
If the reader is consistently purple or red, try rebooting by unplugging and replugging back in. If this persists, repeat twice. After three attempts, check your WiFi connection, and try a different power outlet in your room. If the issue is still not resolved, email engineering@joinmoov.com.
