The new fingerprint Scanner from Samsung works well. Would be great to unlock 1password using the scanner instead of typing the password.
PayPal's Android app supports the scanner, I understand. Please see if this feature support can be in your road map, there should be fingerprint Scanners in several phones in 2015. I remember 1Password for Mac used or contemplated fingerprint Scanner based unlock a long time ago ....now many be the time. ..hopefully Apple will open support to selected 3rd parties too.
