How do I link my business card?

I want to link my personal business MasterCard to my square. It's not affiliated with a bank. It's through Pro-Pay. How do i do it?

For normal Squar deposits you must link to a Transactional bank account so they can credit and debit it.

for instant deposit (which has an additional 1% fee) you must link a debit card.
