Credit Card Glossary: Terms and Definitions
Key is a term used in the data storage and encryption that takes place during the credit card authorization process. Keys, as the name implies, lock and unlock — in this case, data. When credit card numbers are stored or transmitted, they are electronically disguised to prevent thieves from stealing them. One commonly used method is the triple DES encryption, which has a 192-bit key.
