Thank you for reaching the Community, sara74.
I'd like to share some information about card readers in QuickBooks Online (QBO).
For regions like UK, you can process online payments through Paypal and GoCardless Direct Debits. The card reader is currently available only in US versions.
You can check out for card reader manufacturer that can be sync with QBO UK version.
I've also included this link where you can check for the best online payment system in your region.
Feel free to let me know if you still have other questions. I'll be here to help. Have a great day!
