FAQs about Payment Security

What constitutes cardholder data?

Cardholder data refers to any personally identifiable information (PII) associated with a payment card. This includes the primary account number (PAN), expiration date, cardholder name, and service code. Additional information, such as the cardholder’s address or card verification value (CVV), may also be considered cardholder data depending on the applicable security standards.

How can encryption be used to secure cardholder data?

Encryption is a crucial security measure that protects cardholder data from unauthorized access. By transforming sensitive data into an unreadable and encrypted format, encryption ensures that even if the data is intercepted, it remains useless to unauthorized individuals. Encryption requires the use of encryption algorithms and keys to both encrypt and decrypt the data as needed, ensuring secure storage and transmission of cardholder data.

What is the role of tokenization in payment security?

Tokenization is a process where sensitive cardholder data is replaced with a non-sensitive equivalent known as a token. The tokenization process involves generating a unique identifier for the cardholder data and storing the actual data securely in a centralized token vault. Tokens are then used in place of the actual cardholder data during transactions and storage.

Tokenization reduces the risk of exposing sensitive cardholder data by limiting its presence in systems and networks. Even if a breach occurs, the tokens are useless to attackers as they cannot be reversed back into the original cardholder data. Tokenization is an additional layer of security that complements encryption and helps protect cardholder data throughout its lifecycle.
