Fingerprint scanners are convenient and secure, but blocked access can be a bear.
With this in mind, we devised some new tests to measure the convenience and accuracy of log-ons with a biometric fingerprint reader. We ran the tests in our labs under typical office lighting conditions. We also looked for any demographic trends that could lead to enrollment failures with a particular unit. Despite reports to the contrary, we didn't notice any racial or gender patterns. We tried to enroll each finger five times before counting it as a failed enrollment attempt.
