Classic Cloud Token Framework
The Cloud Token Framework (CTF) is the framework for binding a device and a network
token. CTF enables merchants to perform one-time issuer identification and verification
and securely binds a user's device to a Visa network token. CTF reduces fraud rates and
improves transaction conversion.
IMPORTANT
CTF is supported only in mobile in-app experiences.
Prerequisites
In order to send device binding requests, you must have a self-signed certificate
associated with your merchant account. See Cloud Token Framework Key Generation.
A token requestor must pass local authentication information. The token requestor can
select up to two of these authentication factors for the cardholder to verify their
identity at checkout:
- Knowledge
- Knowledge verification factors include information that only the cardholder knows. For example, a password.
- Possession
- Possession verification factors include something that only the cardholder has. For example, a pre-registered mobile phone, a card reader, or a key generation device.
- Inherence
- Inherence verification factors include something that the cardholder is. For example, biometric data. Biometric data includes facial recognition, a fingerprint, voice recognition, or a behavioral biometric.
IMPORTANT
In markets where two-factor authentication is a regulatory
requirement, token requestors must send both authentication factors and the two
selected factors should be mutually independent. In all other markets, token
requestors will have to perform single-factor authentication as a minimum
requirement.
