When you overpay your credit card, we will need to manually process your overpayment which will delay the processing time by an extra day. You will have access to funds from that payment after the over-payment has been processed. It's important to note that overpaying your credit card doesn't increase your credit limit. You will only have access to your approved card limit and the overpayment will be applied to any transactions and fees that appear on your next account statement.
For example, if your credit limit is $500 and your credit card balance is $200, when you send a payment of $300 and overpay by $100, your credit limit doesn't increase to $600. Your limit remains at $500, and the extra $100 you paid will be used to pay for purchases on your next statement.
