A card can take money in a different way from paying money out
A debit card can be used to fund a payment when the cashier, card issuer and operator all support that transaction. A withdrawal may instead be returned to the original card, routed through a card-to-card service or sent to another eligible method. Those are not interchangeable, and the cashier’s current options should state which one applies.
Before a deposit, check the card type, online-payment settings, bank restrictions and any currency-conversion term. If the payment is declined, record the exact message and ask the issuer whether it declined the transaction. Avoid repeating it several times: repeated attempts can trigger further security controls.
Before a withdrawal, ask whether the card can receive the particular transfer and what reference will appear. If the operator marks the payment complete but it is absent, request a trace and ask the issuer to search by reference.
Credit and debit cards are not the same
The UKGC credit-card gambling ban is about credit-card payments, including credit-card funds channelled through an e-wallet. It does not make every debit-card payment available or guarantee that a card will accept a payout. The bank and operator still control their own methods and terms.
For a payment that was not authorised by you, see card-payment disputes. A dispute about gambling losses is different from an unauthorised transaction.
