Yes, You can add only 3 Fingerprints, But There is a drill You can add all Fingerprints too. When you are registering The fingerprints, In the first Fingerprints Scan you left thumb and right Thumb both, simultaneously. You can add both of your thumbs in One fingerprint only. Then in 2nd one You can add your other fingerprints that you want to scan. And in the 3rd also same. I think You can register all your fingerprints. Hope you Got This.
