FILTER BY TAG

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.
