I cannot connect the card reader to my tablet in the app. What am I doing wrong?

I’ll go over how we can work around getting your card reader connected to your app, @honeymountaincof.

Since you've already tried pressing and holding the power button until it's green, you'll want to remove the device from its dock before pressing it. I've got a couple of steps to help you get around this issue.

First, disconnect and reconnect your card reader. Before doing so, look at your app first. If it's green, follow the steps below:

1. From the menu, select Settings.
2. Choose Card Readers, then select the card reader to disconnect.
3. From the Reader Actions drop-down, click Forget Reader.
4. Reconnect the card reader.

If you see blue, here's how:

1. Click More, then select Hardware.
2. Choose Card Readers, then choose the card reader you want to disconnect.
3. From the Readers Actions drop-down, click Forget Reader.
4. Reconnect the reader.

From there, please ensure that your Bluetooth is enabled. Then, repeat the steps to turn on your card reader. For more step-by-step details about this process, please check out this article: Fix issues with the GoPayment and QuickBooks mobile app card reader. 

If the issue persists after trying out these steps, I'd suggest reaching out to our QuickBooks Payments Support team. This way, they'll be able to investigate this matter further and guide you on the best process to fix this query.

Furthermore, here's an article you can refer to on taking payments with QuickBooks Card Reader for future reference: Process payments with the QuickBooks Card Reader.
