Hi there, @RUFRAN,

I appreciate the in-depth details you've added about the credit card reader you purchased. I want to make sure you have the right product that best fit your organization so you can resume your work.

The QuickBooks Payments card readers require compatibility specifications with the operating system and regions. Since you purchased a product that is not compatible with your current location, it would be best to get in touch with our QuickBooks Payments Team.

They have the resources to check your Payments account with us and can help you return the product. Our representatives can also recommend the best application for your credit card processing.

Here's how to contact us: Contact QuickBooks Payments

That should do it. Please update me on how the call goes. The Community has your back, and I'd be more than happy to provide additional assistance if you ever need one. Have a good one!
