Understanding the Lights

  • One red light = Low Battery
    If you see a single red dot on the reader, that means your device is getting power but needs to charge. Just plug it in and leave it alone for at least 30 minutes before trying to pair or use it again.

Step-by-Step Troubleshooting

  1. Use a Wall Outlet
    Plug your reader directly into a wall outlet, not a computer or a power strip. Some power strips may not deliver enough consistent power.

  2. Check the Plug Connection
    Ensure the charging cable is firmly inserted. If you see any silver metal showing or the plug doesn’t sit flush with the reader, it may not be connected properly. Unplug and firmly plug it back in

  3. Give It Time

    If there’s still no light, leave the reader plugged in for 1 hour to allow it to charge. Avoid using it during this time.

How to Verify Your Reader is Charging

On your kiosk:

  1. Tap the three-line menu

  2. Go to Manage Reader

  3. Look under “Battery” — if you see a lightning bolt, your reader is receiving power.

Why This Happens

The EMV puck is frequently handled and may get jostled throughout the day. Sometimes the charging cord can get slightly unplugged without you realizing it. To avoid issues, we recommend leaving the puck plugged in overnight so it’s ready for a full day of use.
