Paypal is an e-wallet. It connects to your bank account or credit card. It will remove transactions from your credit or bank balance. You can accept withdrawals and refunds from your Paypal account as well. Withdrawals may take a little longer than, say, a wire transfer, but it will protect your valuable information. Because of how Paypal works, your casino of choice will link to your Paypal account instead of your bank or credit card. In this manner, you will keep your banking and credit card information more secure as the casino will only see your Paypal account.
