(Europay, MasterCard and Visa) The international standard for smart credit and debit cards that have a built-in microprocessor (chip cards). Governed by EMVCo LLC. (www.emv-usa.com), the EMV smart card provides greater safety than a magnetic stripe card because it uses more sophisticated security methods. EMV supports encryption as well as tokenization, which dynamically assigns a number to the transaction in order to hide the customer's card number (primary account number). Authorization Methods When making a purchase, Chip and PIN systems require card holders to enter their personal identification number (PIN) into the merchant's terminal. Chip and Signature requires a user's written signature. See smart card and gold chipped supercomputer.
