Credit Card Security: How Payment Data Is Safeguarded

Credit card security protects payment data and transactions through safeguards across the payment environment. Learn what PCI DSS covers and how its controls differ from chip acceptance, 3-D Secure, and point-to-point encryption.

Credit card security is the set of safeguards that protect payment-card data and payment transactions from unauthorized access, disclosure, and use. It covers more than the physical card: protections can apply when data is collected, transmitted, stored, and used to authorize a payment. For organizations handling payment data, PCI DSS sets a baseline of technical and operational requirements; it does not guarantee that every transaction is risk-free.

What information does credit card security protect?

PCI Security Standards Council (PCI SSC) distinguishes between cardholder data and sensitive authentication data. The distinction matters because the two categories have different handling rules.

  • Cardholder data (CHD) includes the primary account number (PAN), cardholder name, service code, and expiration date.
  • Sensitive authentication data (SAD) includes full track data or its chip equivalent, card verification codes, and PIN or PIN-block data.

PCI SSC lists these categories in its FAQ on PCI DSS and bank account data.

What is PCI DSS, and who does it apply to?

The Payment Card Industry Data Security Standard (PCI DSS) is a baseline of technical and operational requirements designed to protect payment account data. It is intended for organizations that store, process, or transmit cardholder data or sensitive authentication data, and for organizations that can affect the security of the cardholder-data environment. That environment can therefore include more than the systems that directly handle card numbers.

PCI DSS is an organizational security standard, not a consumer guarantee or a certification that makes a payment environment immune to attacks. Whether an organization must comply or validate its compliance is determined by the entities managing the applicable compliance program, such as a payment brand or acquirer. See the PCI DSS overview for the standard’s scope and purpose.

What kinds of protections does the standard require?

PCI DSS organizes security work across the payment environment rather than relying on one tool. Its 12 key requirements address areas such as:

How should payment data be stored and encrypted?

Do not retain sensitive authentication data after authorization

PCI DSS prohibits storing SAD after a transaction has been authorized, even if the data is encrypted. For cardholder data that an organization does retain, retention should be limited to what is needed for legal, regulatory, or business purposes; data should be securely deleted or rendered unrecoverable when it is no longer needed. PCI SSC says the standard does not set a universal minimum or maximum retention period. The organization must establish an appropriate period for its circumstances. See the PCI SSC FAQ on cardholder-data retention.

Encryption helps, but does not by itself remove PCI DSS scope

Strong cryptography can make cardholder data unreadable, but encrypting it alone does not automatically take the data or the systems involved out of PCI DSS scope. PCI SSC explains this limit in its FAQ on encrypted data and PCI DSS scope. Encryption is one protection within a broader security environment, not a substitute for assessing that environment.

How do chip cards, online authentication, and encryption differ?

These mechanisms address different parts of a payment. They complement one another; none is a replacement for PCI DSS.

Mechanism Where it acts What it does
EMV chip acceptance In-person card acceptance Can reduce some face-to-face fraud, but does not by itself protect the confidentiality of cardholder or sensitive authentication data or fulfill PCI DSS requirements. See PCI SSC guidance on PCI DSS applicability in an EMV environment.
EMV 3-D Secure (3DS) Online, card-not-present purchases A messaging protocol that enables consumer authentication with the card issuer. The PCI 3DS Core standard applies to entities performing specified 3DS functions. See the PCI 3DS Core overview.
Point-to-point encryption (P2PE) From data capture at the merchant device to a secure decryption environment Encrypts payment data at capture and keeps it unreadable until secure decryption. A PCI SSC-listed P2PE solution can reduce applicable PCI DSS requirements; it does not make every other security obligation disappear. See the PCI P2PE overview.
PCI DSS Across the relevant cardholder-data environment Sets organizational requirements covering the protection of payment data and the systems and processes that can affect its security. See the PCI DSS overview.

What does credit card security mean for a cardholder?

It means that multiple organizations and controls may be involved in protecting payment information, but their responsibilities differ. A merchant may secure its payment environment; a processor or service provider may handle payment data; and an issuer may participate in authorizing or authenticating a transaction. A chip, an online authentication step, or encrypted transmission addresses only particular risks or stages. The PCI SSC material described here defines the organizational standards and mechanisms; it does not establish a universal personal checklist or show that any specific consumer product is necessary.
