What is a COF Token?

A credential-on-file (COF) token is a secure digital representation of a customer's payment card information, stored by merchants or payment service providers to safely process recurring payments or future transactions without repeatedly asking for card details.

COF tokens replace sensitive card data, such as the Primary Account Number (PAN), with unique, non-sensitive identifiers. These tokens:

• Protect Sensitive Information: They significantly reduce risks by preventing actual card numbers from being stored in merchant databases.
• Streamline Transactions: Enable quick and seamless recurring payments, subscription billing, and frictionless checkout experiences.
• Enhance Security: Include security measures like dynamic cryptograms and device-specific restrictions, making stolen tokens virtually unusable.

Popularly implemented by global payment networks like Visa, Mastercard, and American Express, COF tokens integrate seamlessly with modern authentication standards such as passkeys, enhancing both transaction security and user experience.

Credential-on-file tokenisation is designed to secure payment information stored by merchants, digital wallets, and subscription services. The process typically follows these steps:

1. Token Creation: When customers initially provide their card details (e.g., during signup for a subscription service or a first-time purchase), merchants request a COF token from the card issuer or payment network. The card network generates a unique token linked specifically to that card, merchant, and user account.

2. Secure Storage: Merchants store the COF token instead of the actual card number. Tokens are encrypted and worthless if intercepted, minimizing risk during data breaches.

3. Transaction Processing: When future payments or recurring billing cycles occur, merchants submit the stored COF token to the payment network. The network securely maps the token back to the original card number and authorizes the transaction without ever exposing sensitive card details.

Credential-on-file tokenisation provides substantial benefits for consumers, merchants, and financial institutions:

• Improved Security and Reduced Fraud: Since tokens have limited use and can't easily be exploited, COF tokenisation significantly lowers fraud risks compared to storing actual card numbers.

• Simplified PCI Compliance: Merchants face fewer compliance burdens under PCI DSS standards since sensitive card data isn’t directly stored on their systems.

• Better User Experience (UX): Tokens simplify checkout processes, allowing for one-click payments, subscription renewals, and frictionless payment flows, reducing cart abandonment and improving customer satisfaction.

Credential-on-file tokens integrate smoothly with contemporary security frameworks, particularly those leveraging advanced authentication techniques:

• Passkey Authentication: Passkeys add an extra layer of security to COF tokens by providing strong cryptographic authentication, reducing risks associated with password-based systems.

• Biometric Verification: Combining biometrics (fingerprints, facial recognition) with COF tokens enhances the convenience and security of recurring and in-app payments.

• 3D Secure and SRC 2.0: COF tokens effectively integrate with protocols like 3D Secure and Secure Remote Commerce (SRC 2.0), streamlining secure, frictionless digital transactions.

Common examples of COF tokens in action include:

• Subscription Services: Platforms like Netflix, Spotify, or SaaS providers use COF tokens to securely handle monthly subscription fees without repeatedly asking customers to input payment details.

• E-commerce Checkouts: Online marketplaces like Amazon or Shopify securely store tokens to facilitate quick, one-click checkouts and effortless recurring purchases.

• Mobile and Digital Wallets: Payment services such as Apple Pay, Google Pay, or Samsung Pay store COF tokens for frictionless, secure transactions both online and in-store.

Credential-on-file tokens combined with modern authentication standards like passkeys represent a powerful and secure approach to payment processing, aligning merchants, financial institutions, and consumers around safer, frictionless digital transactions.

Credential-on-file tokenisation replaces stored sensitive payment details with secure tokens, enabling secure, convenient recurring or future payments without exposing actual card numbers.

Storing tokens rather than actual card data significantly reduces risks associated with data breaches and fraud, and simplifies compliance with security standards such as PCI DSS.

COF tokens facilitate seamless checkout experiences, enabling one-click transactions, subscription billing, and frictionless recurring payments without repeatedly entering card details.

COF tokens have built-in security measures like limited usability, dynamic cryptograms, and merchant-specific restrictions, making them largely useless if stolen.

Integrating COF tokens with passkeys provides strong, phishing-resistant authentication, further enhancing transaction security and user convenience by eliminating traditional password vulnerabilities.
