MasterCard SecureCode

Protect your MNB Debit MasterCard® on the internet with MasterCard® SecureCode™. MasterCard® SecureCode™ is an online security service to protect you against unauthorized use of your MNB Debit Card while shopping online at participating merchants.

Once you've registered and created your own private SecureCode™, you will be automatically prompted at checkout to provide your SecureCode™ each time you make a purchase with a participating online merchant. Your SecureCode™ is quickly confirmed and then your purchase is completed. Your SecureCode™ will never be shared with the merchant. It's just like entering your PIN at an ATM.

When you correctly enter your SecureCode™ during a purchase at a participating online merchant, you confirm that you are the authorized cardholder and your purchase is then completed. If an incorrect SecureCode™ is entered, the purchase will not be completed. Even if someone knows your debit card number, the purchase cannot be completed without your SecureCode™ at a participating merchant. To learn more, go to MasterCard® SecureCode™.
