Yup - you can withdraw cash at any ATM with your card.
Just select the "CR" button. Once you've selected the amount you want, type in your PIN and press "Enter".
The balance on your card is automatically updated any time you withdraw money at an ATM or use it to make a purchase online or in-store. The purchase amount and applicable fee are automatically deducted at the time the transaction is approved. You can always check your card's balance in your Member Area - via your mobile device or computer.
