What is Mastercard 3D Secure?

Mastercard 3D Secure makes it easy and more secure for you to pay with your thinkmoney prepaid Debit Mastercard® online – even when shopping on your mobile.

On occasion, you might be asked to enter a 'One Time Passcode' (OTP) when you pay on a retailer's website. We'll either text or email your OTP to you – you can select which method you prefer at the time you are making your purchase.

If your email address or mobile number has recently changed, you can update these details on Online Account Management by clicking on Personal Details.
