Please check your credit card details. Did you choose the correct card type? Is your credit card number correct?
After entering your credit card details, you may be asked for an additional "SecureCode" or "NetCode". This is an added safety service provided by your credit card issuer. For any inquiry concerning these services, please contact them directly. After entering the code, you will be directed to the order confirmation page.
For your safety, every payment is verified and fraudulent transactions are rejected. In rare cases, a valid payment may be blocked. This process is initiated by your credit card company and not by Springer Nature. To resolve the issue, you will need to contact your card issuer. If the problem persists, please try another credit card, use PayPal or order by advance payment if possible.
If you experience issues with the credit card payment during the purchasing process you should be shown a Payment Reference Code (PRF-XXX-XXX). If you are unsure if the payment worked or not, please provide this number to our Customer Service. Further, not correctly authorized credit card payments are refunded automatically after 28 business days.
