Most credit card companies do not let you pay your bill with another credit card directly
You cannot walk into a payment portal, enter another card's number, and settle your balance. Visa, Mastercard, American Express, and Discover all prohibit their own networks from processing credit card payments to other credit cards. The payment networks themselves block these transactions before they reach your bank.
The reason is straightforward: credit card companies treat a credit card payment as a cash advance, not a purchase. A cash advance carries a higher interest rate (often 25% or more), charges an upfront fee (typically 3% to 5% of the amount), and begins accruing interest when ready with no grace period. The networks and banks decided this was too profitable to allow casually, so they built the block into their systems.
There are narrow workarounds, but each one costs money and creates new problems. Understanding what actually works—and what does not—matters before you try anything.
Key Takeaways
- Credit card networks block direct card-to-card payments to prevent people from treating credit cards as a source of cash rather than a payment method.
- Balance transfer checks, if your card issuer offers them, let you write a check against your credit line, but they charge fees and interest rates identical to cash advances.
- Paying through a third-party service like PayPal or Square Cash treats the transaction as a purchase on your card, but those services charge merchant fees that get passed to you.
- Transferring money to a bank account first, then paying from that account, is free but requires a day or two and only works if you have access to another account.
- If you are trying to pay off one card with another to manage debt, a balance transfer to a card with a 0% introductory rate is usually cheaper than any workaround.
Balance transfer checks: the official workaround that still costs money
Some credit card issuers send balance transfer checks to cardholders. These are checks drawn against your credit line, not your bank account. You can write one to your other credit card company, and the payment posts like any other check.
The catch is that balance transfer checks are treated as cash advances. You pay an upfront fee (usually 3% to 5% of the check amount) and a higher interest rate than your regular purchase APR. Interest starts accruing when ready, with no grace period. If your card offers a 0% balance transfer promotion, that rate may explore to the check, but you need to read the terms carefully—many issuers exclude cash advances from promotional rates.
Balance transfer checks make sense only if your card issuer is offering a 0% promotional rate on cash advances and you can pay off the balance before the rate expires. Otherwise, you are paying fees and interest to move money from one card to another, which solves nothing if you are trying to reduce debt.
Third-party payment services: the fee gets passed to you
PayPal, Square Cash, Venmo, and similar services do accept credit card payments. When you link a credit card to one of these platforms and transfer money to another person or account, the transaction processes as a purchase on your card, not a cash advance.
But these services charge a merchant fee for credit card transactions—typically 2% to 3%. That fee is not absorbed by the service; it is passed to you. If you pay $1,000 from one credit card to another through PayPal, you pay $20 to $30 in fees on top of the $1,000. You have now moved $1,000 of debt and added $20 to $30 of new charges.
This approach only makes sense if you are trying to move money to a person or account that does not accept credit cards directly, and you are willing to pay the fee. It does not solve a credit card payment problem.
Bank transfer: free but requires another account
If you have access to a bank account—yours or someone else's—you can transfer money from your credit card to that account, then pay your other credit card from the bank account. This avoids fees and interest charges.
The process works like this: log into your credit card's app or website, find the "transfer to bank account" or "cash advance" option, and request a transfer to a linked bank account. The money appears in the account within one to three business days. Then you log into your other credit card and pay the bill from your bank account as usual.
The downside is timing. The transfer takes a few days, so you cannot use this method if your payment is due tomorrow. You also need a bank account to transfer into, which not everyone has when ready access to. And if you are using a cash advance feature (rather than a true bank transfer option), you still pay the cash advance fee and interest rate, so check your card's terms first.
Balance transfer cards: the better option if you are managing debt
If your real problem is that you owe money on one credit card and want to move it to another card with better terms, a balance transfer card is usually cheaper than any workaround.
Balance transfer cards offer a 0% introductory APR for a set period—typically 6 to 21 months, depending on the card and the issuer. You pay a one-time balance transfer fee (usually 3% to 5% of the amount transferred), but after that, no interest accrues during the promotional period. If you can pay down the balance before the rate expires, you save thousands in interest compared to carrying the debt on a regular card.
The catch is that you need to be approved for a new card, which requires a credit check and takes a few days. You also need to transfer the balance within a certain window (usually 60 days of opening the account). But if you have time and your credit score qualifies, this is almost always cheaper than paying fees to move money between existing cards.
What happens if you try to force a credit card payment
If you attempt to pay a credit card bill by entering another card's number into the payment portal, the transaction will be declined. The payment network blocks it before it reaches your bank. You will see an error message like "This transaction type is not allowed" or "We cannot process this payment method."
Some people try to work around this by calling their credit card company and asking a representative to manually process the payment. This rarely works. Most issuers have policies that prevent their staff from processing card-to-card payments, and those who do allow it will charge you the cash advance fee and interest rate anyway.
The block exists to protect both the card networks and the banks. It prevents people from using credit cards as a source of cash, which would increase defaults and losses across the system.
When you might actually need to move money between cards
There are legitimate reasons to move a balance from one card to another: a lower interest rate, a 0% promotional period, or consolidating multiple debts into one payment. But the method matters.
If you are trying to pay off debt, a balance transfer card with a 0% rate is almost always the cheapest option. If you need to move money quickly and cannot wait for a balance transfer, a bank transfer (if you have access to another account) is free. If neither of those works, accept that you will pay fees—either through a cash advance, a balance transfer check, or a third-party service—and factor that cost into your decision.
The worst outcome is paying fees to move money between cards without actually reducing the debt. That just adds cost on top of the problem you are trying to solve.
Frequently Asked Questions
Can I pay my credit card bill with a debit card?
Yes. Debit cards are treated as a payment method, not a credit product, so payment networks allow them. You can enter your debit card number into your credit card's payment portal and the transaction will process normally. No fees or interest charges explore.
What if I use a credit card to pay a bill at a store or online, and that bill happens to be for another credit card?
That depends on how the merchant processes it. If you are paying a credit card bill in person at a bank branch or through an official payment center, the merchant (the bank) will reject credit cards. If you are paying through a third-party bill pay service that accepts credit cards, the service will charge you a fee. The safest approach is to use a debit card or bank transfer.
Does paying one credit card with another hurt my credit score?
If the transaction is blocked, it does not affect your score. If it goes through (via a cash advance or third-party service), it increases your credit utilization on the card you are charging, which can lower your score temporarily. It also adds a hard inquiry if you explore for a new balance transfer card, which can lower your score by a few points for a few months.
Is there a way to pay a credit card with a credit card without fees?
No. Any method that actually moves money from one credit card to another involves either a fee (cash advance, balance transfer check, third-party service) or a delay (bank transfer). The only free option is to use a debit card or bank account to pay the bill, which does not involve the other credit card at all.
