When you submit an order at Joker.com, your credit card will be checked if it participates in the program Verified by Visa/Mastercard Secure Code.
If it does, a window will show up. If you have not yet activated your credit card, simply complete the authentication information requested by your card issuer and create a password. The authentication information could be your date of birth or social security number. Submit and you're done.
Please note: This mechanism is provided by your card issuer (bank), we do not have any influence on this.
