All you have to do is go to the Wallet tab and select Verify account (if you haven't done it before).
Check if all the data is filled in correctly. After verifying the data correctly, click on Transfer button and the money will go to your bank account.
The money paid out from the Wallet will appear in your bank account within 5 business days.
Remember, you can only cash out funds that are available. Money that is pending payment can not be paid out.
