Thanks for getting back to us, @TaxCatSC. 

If you're using our GoPayment app to collect payments, you'll need to purchase the mobile QuickBooks Payments EMV Card Reader. 

As mentioned by my peer @AlcaeusF on his post, QuickBooks only supports Magtek card reader via USB through mobile and it can also be plugged directly to a computer without using a USB hub or extension.

For more information, you can also read through this article: EMV Standard and Smart Chip Cards. It includes links to different topics that help you learn about EMV connection. 

Should you have additional concerns, feel free to message us again. We're always around to help.
