Card on file
Card on file means a payment card whose details a merchant, here a casino or sportsbook, has stored after your first payment so you can pay again without re-typing the number. In practice the operator rarely keeps the raw card number; it usually holds a token issued by its payment gateway or by the card scheme itself. For Irish players this matters at the cashier, because the saved card often becomes the default route for both deposits and withdrawals, and because only a debit card can sit there at a licensed operator.
How a stored card works in the cashier
The card goes on file during your first deposit. You type the full number, expiry date and CVV, tick a box agreeing to save it, and complete whatever authentication your bank asks for, often a push confirmation in the banking app. The card schemes call this the initial cardholder-initiated transaction, and every later use of the stored details points back to it.
After that, the cashier shows the card masked, usually as the last four digits.
A later deposit is still a payment you start yourself, so it counts as cardholder-initiated even though you no longer type the number. Mastercard’s gateway documentation separates these from merchant-initiated payments, where the merchant charges without you present under a prior agreement, such as a subscription. A casino deposit does not fit that second category, and an operator that started topping up your balance on its own would be doing something quite different from storing your card. Some cashiers still ask for the CVV on each deposit, and your bank may ask for strong customer authentication again; practice varies between operators and between banks, so there is no single standard flow.
The Irish credit card rule
Since 5 February 2026, section 165 of the Gambling Regulation Act 2024 has barred licensees from accepting credit card payments, including electronic payments that use money loaded from a credit card. A credit card cannot be the card on file at a licensed Irish operator, and neither can a wallet funded from one.
Saved card versus entering it each time
The real choice at the cashier is between letting the operator keep a token and typing your card details on every deposit. Here is how the two compare on the points that affect your money.
Card on file | Card entered each time |
|---|---|
| Deposit takes a tap or two once the card is saved | Full number, expiry and CVV typed on every deposit |
| Operator holds a token, not usually the raw number | Details pass through the cashier every single time |
| Easy repeat deposits can make spending feel lighter | Typing the number adds a small pause before each deposit |
| Withdrawals are often routed back to the saved card | Withdrawal route still depends on the card used to deposit |
Withdrawals and the closed-loop rule
Many operators apply a closed-loop policy, sending withdrawals back to the method you deposited with. Your card on file then becomes the destination for winnings as well as the source of deposits. The terms differ by site, so read the payments page before assuming a withdrawal can go anywhere else.
Where a withdrawal usually stalls is the check before payout, not the card itself. An operator may ask for proof that the saved card is yours, typically a photo with the middle digits covered, and the payout waits until that document is approved. If the card has expired or been replaced since you saved it, the operator may need you to add the new one before it pays out, and some will route the money to a bank transfer instead.
Removing a stored card is normally done in the account or cashier settings, and some sites ask support to do it.
Terms often confused with card on file
Card on file gets mixed up with three neighbouring ideas, and each mix-up leads to a different wrong expectation. A saved card in Apple Pay or Google Pay lives on your phone, not with the operator, and the casino sees a device token rather than your card. Recurring billing is a merchant-initiated charge, which a gambling deposit is not.
Tokenisation is the method, not the term itself.
The third confusion is with a bank-level gambling block. Most Irish banks and card providers now offer a block that refuses gambling transactions at card level, and it overrides any card an operator has on file. If you want a stored card to stop working at casinos, the block in your banking app does that whatever the cashier shows, while deleting the card on one site only affects that site.
