Duo (2nd Generation) Troubleshooting

Unable To Pair Device

  1. Hold down the power to reset the device.

  2. Check if you can find the device’s “Serial Number” (shown on the bottom of the device) in the Bluetooth devices list of your tablet.

Duo Loses Connection With Tablet

  1. Press and hold the power button to turn the device on. If you disconnected because of the “auto-off” feature, turning the device back on will reconnect it.

  2. The device may have a low battery, so charge the device by connecting the USB cable to the included power brick to charge. Do not charge on a computer or mobile device as this will not provide a sufficient charge for the device.

  3. Ensure the computer and iPad is within range of the device.

Duo Card Reading Issues

  • Press the power button to turn off the device, then turn it back on. The device will automatically reconnect with your tablet.

  • The device may have a low battery. Use the USB cable and power brick to recharge it, then retry.

  • Ensure the device, computer, and iPad are all within range of each other.

  • Check if the device has power and ensure it’s connected to both the iPad and computer.

  • Make sure the app is instructing you to swipe, insert, or tap a card.

  • Ensure there is no dust/debris in the card slots.

  • Check if the magstripe or chip of the card is facing the right direction when swiping or inserting the card.

  • Ensure that your iPad OS version is supported (the Duo app requires iOS 13+ for use)

  • Try swiping or inserting the card at a different speed.

  • If tapping, ensure that your card supports NFC (aka tap-to-pay).

  • If tapping, ensure that your card is within 4 cm of the NFC marking.

  • If tapping, remove your card from your wallet or purse to avoid any interference.

Duo Not Responding

  • Use a paperclip or a narrow, pointy object to hold down the reset button for at least 15 seconds. Repeat the pairing process if necessary and try again.
