A transfer with iDebit is instant. This means that you can start playing casino games for real money after the transaction has been confirmed by your bank.
When you request a withdrawal, you need to keep in mind the withdrawal processing times from the casino, as it may take some time for them to check the withdrawal. The casino may also ask you to verify your identity by sending them a photo or scan of your documents, such as a passport and proof of address.
Once processed by the casino, the withdrawal is quick as well, and the money should be available in your iDebit account within a few minutes.
