We can enroll maximum 2 Fingerprints per user.

Please Note : This setting is fixed, once we have selected this and enrolled users in machine and now we want to change setting that is 1 Fingerprint per user then its not possible, we have to format this device and then we can change setting. Again we have to start from enrollment(Beginning). So its important to decide how many fingers you have to enroll per user before you starts installation.
