All Circleworks online credit card transactions are done using a secure transactions server. We never store (or have any visibility of) your credit card number. When you pay for your order, you will be redirected to Westpac secure page (with 128 bit encryption strength). This is a real-time transaction, so you will know the result of the transaction immediately. You should be returned to the Circleworks website at the end of the process and given a receipt number, if you are not, please contact us.
