We are switching the 3D Secure procedure MasterCard®SecureCode™ to mobileTAN (mTAN) for you.
This will once again improve the security of online purchases you make with your credit card, your mobile phone and a computer.
You can either activate your credit card for the mobile TAN procedure by using the following registration link or when you next make a payment at a participating online retailer. Your existing SecureCode™ (static password) will no longer be valid. You will therefore have to re-register once.
In brief, the shopping procedure is as follows:
- You make online purchases with your credit card as usual.
- You receive a TAN by SMS to your mobile phone. The TAN is valid only for this particular purchase.
- A confirmation window for your purchase opens on the screen.
You check whether the details of your purchase are correct on the screen and in the SMS, and authorise the purchase with the TAN and by answering your additional security question.
If you have any questions when registering for the 3D Secure procedure MasterCard®SecureCode™, the cardholder service can be reached around the clock by dialling +49 (0)69 / 7933-2555.
