Device data includes:
- our confidence that the device identified is a unique device,
- the local time for the device,
- and when it was last seen on your transaction pages.
These data points will only be returned when you have enabled device tracking, and send your request to the minFraud Insights or Factors web services. Learn more about device tracking.
If you're using device risk data for manual review, and you use the minFraud Factors service, you may also find it helpful to consult the device risk factor scores to give you a better picture of the transaction. Learn more about device risk scores.
Device tracking is not always precise. Device tracking works by building a profile of information about a device that could be used to uniquely identify it. However, if the information collected is not distinctive enough, many devices could share the same basic profile.
We return a rating of our confidence that we have identified a single, unique device, rather than a collection of similar devices. This rating is a percentage ranging from 0.01 to 99, so a device confidence rating of 54.3 means that we are 54.3% confident that we have identified one specific device.
If the device confidence is low, you should have less confidence in the other device risk data returned. If it is higher, you can reliably consult the other device data.

Device last seen
The minFraud service keeps a record of when the device was last seen on your transaction pages specifically. You can compare this date and time with your local web session logs to confirm that this device is associated with a particular user, and is not a cluster of devices that may be used by many users.
