What is a dynamic or temporary CVV / CVC?
A dynamic CVC is a temporary Card Verification Code generated in the Westpac App. It changes every 24 hours for security purposes. It’s a different number to the CVC printed on the back of your physical card, but lets you make one-off purchases in the same way. You can also use the dynamic CVC for setting up recurring card payments. When you set up a recurring card payment you provide your card details (including the temporary CVV/CVC) to the merchant. These details are used once only by the merchant (and may be used by the merchant upfront to validate your card details) to set up the recurring payments, and ongoing payments will not be impacted.
