Device fingerprinting

Device fingerprinting is one of the fraud prevention tools. You use this tool to help detect fraudulent behavior.

Generally, you use a device fingerprint for the first transaction with a card. Openpay requires a new device fingerprint to be created with every transaction (included by default with the Nexio iframe), while it is strongly recommended for Kount. For information about device fingerprinting requirements, see the gateway-specific information for the Connections you use.

This section contains the following topics for ways of using device fingerprinting:

• Using device fingerprinting in the save card flow with an iframe
• Using device fingerprinting in the save card flow with your own form
• Using device fingerprinting in the run transaction flow with an iframe
• Using device fingerprinting in the run transaction flow with your own form

Note

If you do not want to use a device fingerprint when using the iframe, set the processingOptions.shouldUseFingerprint parameter to false in the one-time-use token request.
