When an online casino allows deposits via wire transfer, you can fund your casino account by sending money directly from your bank. This method is secure and ideal for large deposits, though it may take a few business days to process. You’ll usually need the casino’s banking details, such as IBAN and SWIFT/BIC codes, to complete the transfer. While not instant like eWallets or cards, wire transfer is a trusted option for players who prefer using their bank for deposits, especially for higher amounts or when other methods aren’t available.
