The Benefits of Biometrics in Access Control
The goal of any access control system is to let authorized people, not just their credentials, into specific places. Only with the use of a biometric device can this goal be achieved.
A card-based access system will control the access of authorized pieces of plastic, but not who is in possession of the card. Systems using PINs require an individual only know a specific number to gain entry; but who actually entered the code cannot be determined.
On the contrary, biometric devices verify who people are by what they are, whether by hand, eye, fingerprint, or voice recognition.
Biometric reductions in errors have lowered the capital costs of ID cards in recent years and the true benefit of eliminating them is realized through reduced administrative efforts. For example, a lost card must be replaced and reissued by someone.
Just as there is a price associated with the time spent to complete this seemingly simple task, when added together, the overall administration of a card system is costly.
Contrary to using badges, sign-ins or other ways of tracking employees, a biometric time clock assures that no employee can punch in for another, eliminating time fraud and reducing payroll costs.
Because every person’s biometric characteristic (hand, fingerprint, eyes, face, etc.) is unique, a biometric time clock provides a quick, accurate, and reliable way to record in-punches and out-punches for each employee. That’s why so many companies now employ biometrics.
