I have one at Chase.

Open a Chase business checking account, it has an option to accept credit card payment.

Three ways to accept:

You type their credit card number in your checking account. 3.5% fee + 10cent

You send a link to them, 3.0% fee (maybe 3.5%)

You buy a reader $50-$300, they scan card 2.6% fee.

Money deposit to your account next business day.
