The Dayforce Touch Clock is equipped with a biometric reader that can be used to capture a mathematical representation of employees’ fingerprints when they perform clock entries. When configured, the clock compares the representations of the fingerprints saved in the database previously and at the time of the clock entry. If the two match, the clock entry is accepted. If they don’t, it’s rejected.
The finger scan biometrics in Dayforce’s terminals can’t be used or manipulated to gain any personal information about the employee, because Dayforce’s biometric terminals don’t reproduce or capture a fingerprint. Instead, a numeric template is produced from unique swirls found in the pattern of the finger print and capillary patterns. The minutia or swirl pattern files can’t be reverse-engineered to reproduce the entire print because information is missing.
There is no stored image or fingerprint on the device or host systems. Rather, the scan is converted to a numeric template that consists only of a string of numbers and letters that is useful only to the device. When a finger is scanned, prevalent points are mapped and recorded. After these points are mapped, they’re assigned a number value based on their location. These values are then fed into an algorithm to produce a biometric template.
The following is an example of what a biometric template looks like when it is uploaded:

As you can see, the employee’s fingerprint isn’t being used. This removes any risk to their identity being compromised and still maintains a very effective way to prevent employees from falsely representing themselves on your time clocks.
