Muffins with dulce de leche sauce. A home-made form of dulce de leche is sometimes made by boiling an unopened can of sweetened condensed milk for two to three hours (or 30 to 45 minutes in a pressure cooker), particularly by those living in countries where it cannot be bought ready-made.
The CVN code is a special 3-4 digit code used as a security measure for all Internet transactions. It is called CVV2 (Credit card Verification Value) for Visa cards and CVC2 (Credit card Verification Code) for MasterCard. Since the CVN is listed on your credit card, but is not stored anywhere, the only way to know the correct number for your credit card is to physically have possession of the card itself. Because of this, it is a security enhancement against misuse of credit cards. All VISA, MasterCard and American Express cards newer than 5 years have a CVN. Note: The CVN code is printed on your card; it is not raised from the surface of the card like your credit card's account number.
The CVV number is the card verification value or security code on a debit card. Major debit card issuers, including Visa, Discover and MasterCard, use three-digit CVV numbers, while American Express uses four digits on its prepaid debit cards. The card companies use different names for these security codes.
