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 fingerprint 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.
