Troubleshooting EMV Card Reader

Battery level

A low battery level can cause connectivity issues which is why we recommend charging your card reader. You can charge the SumUp Air Card Reader with the Micro USB cable included in the package. Just plug it into a power supply or a computer.

The battery level is shown on the display of the card reader as well as through the blue LEDs at the bottom of the reader. To view the battery level, press the power button and quickly release it again. Depending on your card reader’s battery level the LEDs will light up. One LED equals about 25%.

Restart Card EMV Reader

If none of the above solved your connectivity issue you can also restart your reader. This option should be used sparingly. To restart your card reader, hold down the power button of your reader until the lights turn off. Wait approximately 10 seconds. Then hold the power button until the lights come on again and release the power button. There should now be one blinking blue light, indicating that your EMV card reader has restarted.

Important

Never restart your SumUp Air Card Reader while charging as this can damage your card reader.
