Troubleshoot Headphone Jack Dynamo ReaderLast updated on 03/22/2022
Remember: If you can’t get a successful swipe, you can always manually enter the card (or take a picture).
Here are the common troubleshooting solutions to fix swiper issues.
Turn the volume all the way up (most common issue)
After you insert the swiper, make sure the volume on your mobile device is turned all the way up. You will want to turn the volume all the way up and close all other apps on your tablet before using the swiper.
Do not swipe during a phone call
The card reader will not work if the audio on the device is being used elsewhere. For example, you cannot swipe a card during a phone call.
Try disabling Bluetooth on the device. When Bluetooth is enabled, it may prevent the audio jack from transmitting sound (this means the swiper will not work). Turn off Bluetooth by going to Settings > Bluetooth.
Restart your mobile device
If you haven't already, try restarting your phone or tablet.
Disable Siri (Apple products only)
If you are using an Apple device, you may need to turn off Voice Dial (Siri). You’ll need to set a passcode first, if you haven't done so already.
Once you have your passcode, go to Settings > Touch ID and Passcode > Voice Dial. Turn off Voice Dial.
Music Voice Control is always on by default (you cannot turn this off).
If you are using an older device, or if you haven’t set a passcode on your account, voice control may already be turned off.
