Neteller acts as the middle man between the online casino and the player. You register and open an account with Neteller and subsequently fund the Neteller account with your bank debit or credit card.
Your casino account can then be funded by using your Neteller account.
All withdrawals made from your online casino account are then deposited directly back into your Neteller account.
The benefits of using Neteller as your funding option are many. Several online casinos, such as Ladbrokes for example pay your withdrawals pretty much instantly back into your neteller account as soon as you hit the confirm withdrawal button.
Withdrawing monies from your Neteller Account back to your bank account take on average 3 – 5 working days.
