How does fingerprint biometrics work?
When an employee is first enrolled in a fingerprint-based biometric time and attendance system, the software records a template of the employee’s fingerprint and associates that template with the employee’s ID number. This template measures the relationship betweenvarious points in the fingerprint. Each time the employee attempts to clock in or out, the time and attendance software verifies that the newly scanned fingerprint matches the template originally stored for that ID number. If there is a match, the punch is recorded. Occasionally, employees will have privacy concerns about having their fingerprint scanned. The fingerprint templates used for biometric verification such as with ATRx Secure PunchIn are stored in encrypted format and cannot be used to re-create anyone’s fingerprint. Additionally, because biometric verification uses relatively few points of comparison, the templates used in commercial time and attendance systems are useless without another fingerprint with which to
