Check out the different troubleshooting scenarios below to resolve the common issues that cause that kiosk unavailable error.

Troubleshooting

• Step	Process	Image
  1	Double-check card reader is ON (indicated by green light on top front of the reader).
  2	If the card reader isn’t turning on, restart the card reader. Use a pushpin to press  the reset button on the right-side of the cradle.
  3	If the card reader seems to not hold a charge, open the kiosk to access the connection box. Pull out the card reader plug from the power strip.
  4	Plug it into a power outlet for a quick charge. After charging a bit, turn ON the card reader (indicated by the green light).
  5	Plug the card reader back into the kiosk power strip. The kiosk should automatically detect the card reader connection.

   

  Turning Card Reader Off During Non-Operating Hours
  To ensure your card reader is holding a charge, you can turn it off during non-operating hours. This will save battery life and help ensure the card reader is good to go for the opening shift.
