Biometric time clocks are used to identify a user for a time and attendance system. In many cases, biometrics reduces buddy punching and prevents time theft. But in configuring your time clock, there are a couple of options for making the transaction process of identifying the biometric of an employee more smooth.
When you enroll an employee, the biometric template of the finger is stored within a database of the clock. When the employee wishes to initiate a transaction, they place their finger on the bio-metric sensor. In a one to many (1:many) situation, the clock will take the simple action of the finger placement and search through all of the templates on the clock to find the one that matches. This can prove to be a challenge for any clock if there are quite a few biometrics stored in the device.
To aid the search process within the time clock, one to one (1:1) verification is used. The employee is asked to type their badge or PIN number at the clock, immediately directing the clock to correct template. The clock then waits for confirmation by accepting the placed finger and matching the action against the stored template.
