I'm sorry if this has been covered already but I couldn't find it on the threads.
I have an existing business account with which my card reader is connected and I have now got another new business (with separate log in details) and i wondered if i can add the existing card reader to my new business account?
You can, but you'd need to disconnect it from the old one. It's only one account on the card reader at once. Just go through the setup process like before with the reader, entering the new account details in instead.
